It causes pp_entersub to be called in odd places, which can cause the
context stack to be reallocated when an outer function call (like
pp_leavesub) has a pointer into the context stack in a C auto.
cleanup.t was failing for me under PERL_DEBUG_READONLY_COW +

and the old address then freed and reused for something else, being
zeroed in the mean time. So pp_leavesub returned NULL (trying to

PERL_DEBUG_READONLY_COW
Make perls compiled with -Accflags=-DPERL_DEBUG_READONLY_COW to turn
COW buffer violations into crashes.
We do this using mmap to allocate memory and then mprotect to mark
memory as read-only when buffers are shared.
We have to do this at the safesysmalloc level, because some code does
SvPV_set with buffers it allocates on its own via safemalloc().
Unfortunately this means many things are allocated using mmap that
will never be marked read-only, slowing things down considerably, but
I see no other way.
Because munmap and mprotect need to know the length, we use the
existing sTHX/perl_memory_debug_header mechanism used already by
PERL_TRACK_MEMPOOL and store the size there (as PERL_POISON already
does when PERL_TRACK_MEMPOOL is enabled). perl_memory_debug_header is
a struct positioned at the beginning of every allocated buffer, for
tracking things.

[perl #118817] avoid using 2 handles to write to the debug output
Previously the tests were run with the following config:
NonStop=0 TTY=db.out LineInfo=db.out
This meant that the debugger would write the prologue, command prompts
and their results and the epilogue to one handle, and any line trace
information to the second handle. Since those handles didn't share a
file position, the line trace info would overwrite the prologue, and
the epilogue would overwrite part of the line trace info.
When TTY=vt100 on Redhat systems this made the epilogue just long
enough to overwrite the line trace data that a test matched against,
causing the test to fail.
To fix this, I avoided setting LineInfo:
NonStop=0 TTY=db.out
and since LineInfo defaults to using the TTY handle, both types of
content are written to db.out *without* overwriting each other.
Unfortunately this broke some other tests, since the command prompts
which were overwritten by line trace information are now mixed in with
the line traces - I've modified the tests that failed to account for
the included command lines.

regcomp.c: Rmv remaining uses of PL_Posix_ptrs
Previous commits have removed all but a few uses of PL_Posix_ptrs. This
removes the rest. ASCII is the same whether over all code points, or
just the ASCII range, so we can substitute the version for all code
points. There is an extra intersection introduced by this commit during
the construction of a synthetic start class under /a and /aa, but the
performance hit should be negligible.

regcomp.c: Collapse two branches.
Previous commits in this series have removed the need to special case
[:ascii:]. This commit removes the special casing. There is a slight
performance penalty if this is the only POSIX class in the bracketed
class, and is being compiled under /a or /aa: An extra intersection will
be performed. Since this is regex compilation, this should be
unnoticeable.

regcomp.c: Trade a little time for simplicity
Perl currently has two sets of inversion lists for the POSIX classes
built in. One set is for the entire Unicode range; the other for just
the ASCII range. This latter set could be derived from the larger one
at run time by doing an intersection with ASCII. This commit starts the
process of entirely removing the second set, thus avoiding its
bookkeeping. This commit avoids one use of the ASCII set, instead
adding an intersection with ASCII after all the POSIX classes in a
bracketed character set have been combined. Thus the penalty is one
intersection per compilation of each bracketed character classes that
contain POSIX classes.

Keep separate list of posix classes and complements
In building up the list of code points that are matched by a bracketed
character class, there can be both posix classes and complemented posix
classes, like [\s\W]. By keeping each type in a separate list, we can
simplify code in later commits.

Keep temp. separate list of foldable characters
When populating what a bracketed character class should match, it turns
out that if we keep a separate list of code points whose folds may have
to be added, we can simplify the code. This commit just adds the new

We have a section of code already for handling POSIX classes under /l.

in future commits. We still have to special case [:blank:] on platforms
that don't have isblank().

Remove PL_L1Posix_ptrs
This global array is no longer used, having been removed in previous
commits in this series.

outside the core. It has never been externally documented, and is an
opaque structure whose internals have changed with every release. The

few that aren't have been hidden from all but the few .c files that need

Compile in list of foldable code points
When constructing what matches code points under /i, Perl uses an
inversion list of all the possible code points that participate in
folds. This number is relatively few compared to the possible universe
of code points, as most of the world's scripts aren't cased, and many
characters in the scripts that do fold aren't foldable (such as
punctuation). Prior to this commit, the list for the above-Latin1 code
points was read-in from disk if and only if needed. This commit causes
the list to be added to read-only data in a C header, trading a little
space in Perl's text segment for speed at execution. This will enable
ripping out some code in this and future commits (offsetting the space
used by this one).

the largest chunk of this code, used when a POSIX class is used within a
bracketed character class. Later commits will remove more.
