I could reproduce this problem with the following environment.
OS : Ubuntu 8.04
Compiler : gcc 4.2.3
PCRE version : 7.7 (2008-05-07)
* using pcretest
re>/(?x)1|2 #(?<N>3)/I
Capturing subpattern count = 0
Named capturing subpatterns:
0
Options: extended
No first char
No need char
* using the following small C code. (The output result is "ret=0, namecount=1")
re = pcre_compile("(?x)1|2 #(?<N>3)", 0, &errorptr, &erroroffset, NULL);
if (re != NULL) {
ret = pcre_fullinfo(re, NULL, PCRE_INFO_NAMECOUNT, &namecount);
printf("ret=%d, namecount=%d\n", ret, namecount);
} else {
printf("%s\n", errorptr);
}
So I think that this problem does not depend on the environment.
Is the following related to this problem?
[Pcre-svn] [360] code/trunk: Fix CVE-2008-2371 ( outer level option with
alternatives caused crash).
Thanks,
