Update of bug #13847 (project grep):
Status: None => Works For Me
_______________________________________________________
Follow-up Comment #1:
Although this bug is already fixed in CVS, the attached patch suggests the
idea of adding a test for it.
The test itself can probably be shortened to just
echo | ${GREP} -P '\s*$' > /dev/null 2>&1
and a check of the return value in $? (it segfaults when the bug is there). I
leave the * in the pattern since we may eventually want to alter the -P
behavior to perform the equivalent of a Perl chomp on each input line before
attempting the match (and of a Perl print "$_\n" when the line matches).
Should we add a tests/pcre.sh file with a guard at the beginning to detect if
grep was even compiled with HAVE_LIBPCRE and silently skip the whole test file
if it wasn't?
