* [Bug c/14632] New: regcomp function does not return 0 for invalid regular expression

A few tests using regcomp indicate that it is not returning 0 for an invalid
regular expression. For example:
#include <stdio.h>
#include <sys/types.h>
#include <regex.h>
main()
{
regex_t re;
int x;
x = regcomp(&re, "(", 0);
printf("%d\n",x);
}
Run this, x is 0.
if I set the regexp to "*", x is 0 (the man page describes the error code
REG_BADRPT as "Invalid use of repetition operators such as using `*' as the
first character.)
if I set the regexp to "**" or even "((", x is 0.
In fact, I can't input a regular expression that has x return anything other than 0.
Comments?

Unfortunately, regex is not under the control of gcc. You will have to find
the authors of that package and report this with them.
Thanks
