From: "jas at cs dot yorku dot ca" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/14632] New: regcomp function does not return 0 for invalid regular expression Date: Thu, 18 Mar 2004 14:45:00 -0000 [thread overview] Message-ID: <20040318144512.14632.jas@cs.yorku.ca> (raw) 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.
