between plain operations and the optimized string operations. Due to

This allows us to properly build glibc with the current community

Fix _nl_find_msg malloc failure case, and callers.
This patch fixes two issues, and perhaps should be two distinct commits,
but I present it here as one for the sake of completeness.
Commit
006dd86111c44572dbd3b26e9c63dd0f834d7762 fails to check malloc's
return in intl/dcigettext.c (_nl_find_msg):
~~~
freemem_size = INITIAL_BLOCK_SIZE;
newmem = (transmem_block_t *) malloc (freemem_size);
...
newmem->next = transmem_list;
transmem_list = newmem;
~~~
If malloc fails then newmem is NULL then newmem->next results in a
fault.
The fix is easy enough, check for newmem != NULL, and fall through to
the error condition below which returns (char *) -1 e.g. resource error.
The problem is that returning (char *) -1 will break all sorts of other
code, so while what we did is correct, the real failure case fix is
slightly broader.
There are 4 other places where _nl_find_msg is called, one is OK, the
other three are fixed to handle -1 error return value.
No regressions on x86-64 or x86.
However, no regressions isn't really a useful metric for this code.
The change was tested as documented here:
