Moreover POSIX regexp makes the empty string match 'a?', which is not the case
with pcre when PCRE_NOTEMPTY is set.
So the 'correct' patch shall look like:
else
{
so = 0;
eo = strlen(string);
}
+ if (so != eo) options |= PCRE_NOTEMPTY;
rc = pcre_exec((const pcre *)preg->re_pcre, NULL, string + so, (eo - so),
0, options, ovector, nmatch * 3);
