[pcre-dev] bug found in last version (7.9)

[John Brown]

I placed regex and subject in the regex.txt and subject.txt files (see
this email attach)
Code I used (it will fail with stack overflow exception because match()
function uses endless recursion):

    int err;
    const char * errchar;
    pcre * pRegex = pcre_compile("(([^><]|<br>|<p>)+?)<.+?>(?!.*<div
class=\"heading\".*My Info)(?=.*?<td valign=\"bottom\" colspan=\"2\">)",
        PCRE_DOTALL|PCRE_MULTILINE,&errchar,&err,0);

    int vec[1024];
    if (pcre_exec(pRegex,0,SUBJECT,strlen(SUBJECT),0,0,vec,sizeof(vec)))
    {
        free(pRegex);
    }

Thanks.
