Description Tim Waugh 2004-11-09 10:27:23 UTC 
Description of problem:
This program segfaults:

#include <regex.h>
#include <stdlib.h>
int main ()
{
        struct re_pattern_buffer *buf;
        buf = malloc (sizeof (struct re_pattern_buffer));
        re_set_syntax (RE_SYNTAX_GREP | RE_HAT_LISTS_NOT_NEWLINE);
        return !!re_compile_pattern ("\\(\\b\\)\\{0\\}", 11, buf);
}

Version-Release number of selected component (if applicable):
glibc-2.3.3-74

How reproducible:
100%
Comment 1 Tim Waugh 2004-11-09 10:48:02 UTC 
Still segfaults after adding:

memset (buf, 0, sizeof (*buf));

after the malloc line.
Comment 3 Jakub Jelinek 2004-11-10 13:26:56 UTC 
Fixed in glibc-2.3.3-76
Comment 4 Jakub Jelinek 2004-12-23 21:14:54 UTC
