The regcomp function in current CVS and Fedora rawhide no longer accepts
dual-bracket regular expressions.
This piece of code works on GNU libc <= 2.3.5, FreeBSD and OpenBSD without
problems, but with the additional regcomp change that has been done to CVS this
piece of code returns 7, which means a problem with brackets (missing ] while
opened with [ for example). This issue also affects tools like grep.
#include <sys/types.h>
#include <regex.h>
#include <stdlib.h>
#include <stdio.h>
int
main (int argc, char **argv)
{
int err;
regex_t r;
err = regcomp (&r, "[[:space:]]", REG_EXTENDED);
if (err != 0) {
printf("%d\n", err);
}
return 0;
}

Does that testcase really file for you?
I can't reproduce this on Fedora glibc-2.3.5-1 on i686 nor with CVS glibc
on x86-64. regcomp in all cases returns 0.

I get this behaviour with glibc-20050415T0909 as found in Fedora rawhide CVS.
Currently recompiling with other options to make sure it isn't a compile f*ckup
instead of a real bug.

Seems this bug is caused by specific options in ./configure our glibc package
maintainer didn't check.
I changed the build parameters for ./configure to use exactly the same lines as
the specfile in fedora CVS says and now it works fine.
