Fix ‘panic: memory wrap’ in reg_scan_name
reg_scan_name was not checking for end-of-string. If the character it
read were not a word character, it would then increment the current
position (RExC_parse), so that the <-- HERE marker in the error mes-
sage would point to the bad character.
If we try to split a regexp like /(?</ into two pieces when the cur-
rent position is off the end like this:
( ? < \0
^
then the first ‘half’ of the regexp, before the <-- HERE marker is
"(?<\0" (including the trailing null), and the second ‘half’ is of
negative length. Negative string lengths are what cause ‘panic: mem-
ory wrap’.
$ ./perl -Ilib -e '/(?</'

Fix memory leak with recursive sub redefinition

Commits
7004ee4937 and
a61818571 changed subroutine redefinition to
null the GvCV slot before freeing the CV, so that destructors won’t
see GvCV without a reference count. That turns a double free into a
memory leak.
Kent Fredric explains it nice and clearly:
> sub foo{} # A
> bless \&foo;
> DESTROY { *foo = sub {} # C }
> eval "sub foo{} "; # B
>
> Previous behaviour was:
>
> B replaces A, triggers DESTROY, which triggers C replacing A, and this

So C leaks.
This commit fixes it by changing the SvREFCNT_dec into SAVEFREESV,
essentially delaying the DESTROY until after the subroutine redefini-
tion is complete.
This does mean that C is what ends up in the glob afterwards; but as
long as perl’s own bookkeeping is thrown off, we can leave it to the
user (the Perl programmer) to handle the consequences of naughty
destructors.

What is happening is that the first scan goes past the delimiter at
the end of the pattern. Then a single byte is compared (the previous

whether the parser needs to step back one byte before scanning the
second part.

$ ./perl -Ilib -e 'sub foo{} bless \&foo; DESTROY { undef *foo } undef *foo'
Attempt to free unreferenced glob pointers, Perl interpreter: 0x7fd6a3803200 at -e line 1.
by lowering the refcount of the gp only after freeing the contents.
But what was missing was a check at the end to make sure the refcount
was not already 0.
In fact, that can’t work either, as, if the refcount has gone down
to 0 while freeing the contents of the gp, we will be reading
freed memory.
In an attempt to implement what my half-baked idea was meant to do,
I thought of incrementing the reference count before freeing the
entries, and then checking it afterwards, but that would cause an
‘undef *foo’ during that to null the gp slot of the gv and replace it
with a new one. In the mean time, gp_free is only freeing the old gp
and the new gp will leak when it sets GvGP to 0.
I thought of detaching the gp from the gv completely before freeing
its entries, but most code doesn’t expect to see typeglobs with no gp.
GvSV will crash.
I nearly concluded that the only approach I could use was to revert
4571f4a72 and simply extirpate that warning. As far as I can tell, it
only comes up with recursive gp_free calls. However, in those cases,
simply returning will cause a memory leak, as pp_undef will give the
gv a new gp, and the outer gp_free call, when it finishes, will set
the gv’s gp slot to null, overwriting what pp_undef put there (a vari-
ation of the leak above).
So, the final solution is for gp_free to re-read the GvGP value each
time it loops, freeing entries. The reference count will continue to
be decremented at the end of the function, as in
4571f4a72. That will
prevent any bad reads. If pp_undef has reallocated the gp in the mean
time, we will simply start using the new one. We need an extra refer-
ence count check at the end, in case a destructor does glob assignment
and causes the gp to be shared.
Ideally this should fix the recent build errors. (See
<
20131113045538.GA18816@mars.tony.develop-help.com>.) I tried it
under valgrind on dromedary both before and after the patch, and the
bad reads went away.

Opcode: fix 'null argument' warning
HvNAME_get() can return NULL, and strNE() wants non-null args.
[
As a side note: on debugging builds this line
if (strNE(HvNAME_get(hv),"main")) {
macro-expands into an 18,000 character line (!) due to the fact that
HvNAME_get() is quite a big expansion under debugging, and strNE expands to
strlen, which under gcc expands to a huge macro (which is mainly lots of
different compile-time alternatives depending on which of its args are
constants), that references its args several times.

IO.xs: fix compiler warning
PerlIO_unread() returns SSize_t, although from its sparse documentation

File::Glob: fix warnings and non-\0-ended strings
The lower levels of File::Glob expect null-terminated strings, while
the higher levels do s = SvPV(sv,len) and pass the len. Ease the impedance
mismatch by ensuring that s[len] is always \0. Most perl SVs will already
have that \0 anyway, so in practice this hasn't been an issue.
It also ignores the utf8-ness of the string. I've kept that as-is (too big
a can of works to open for now), but I've fixed the 'is_utf8 var not used'
warning and added an XXX comment instead.

File::Glob: silence some compiler warnings
In bsd_glob.c, there are nested set of functions glob0(), glob1() etc,
which among their parameters pass a pointer to a compiled pattern, and also
to its end. It turns out the end pointer isn't usually used, since the
pattern is usually scanned for BG_EOS instead. Also, glob3() is
passed two pattern ranges, both within the same pattern, and both with
the same pointer to the end of the pattern buffer. Since both end pointers
are the same, eliminate one of them. This removed an unused var compiler
warning. Use the remaining end pointer in the glob*() functions to add
assertions that we haven't fallen off the end of the buffer.
Finally, ARG_MAX may be signed.

The renaming of the 'form' arg to 'format' is due to form being #deffed to
Perl_form() or similar.
Some of the unused vars were due to things like BmPREVIOUS() being #deffed
to 0 in recent builds.
The pad ones were due to the PADOFFSET type being used to index a pad
*list*, not a pad - that's SSize_t.

Actually, most of this commit is adding (void) to various function returns
where we know its ok to ignore the return value. This doesn't actually
silence the -Wunused-result warning (thanks a bundle gcc), but at least
it marks our intentions.
