WildcardMatch broken #248

Failing sometimes:

bool WildcardMatch(const char* psz, const char* mask)
{
    loop
    {
        switch (*mask)
        {
        case '\0':
            return (*psz == '\0');
        case '*':
            return WildcardMatch(psz, mask+1) || (*psz && WildcardMatch(psz+1, mask));
        case '?':
            if (*psz == '\0')
                return false;
            break;
        default:
            if (*psz != *mask)
                return false;
            break;
        }
        psz++;
        mask++;
    }
}

Working always:

bool WildcardMatch(const char* psz, const char* mask) {
        loop {
                if (*mask == '\0') return (*psz == '\0');
                else if (*mask == '*') return WildcardMatch(psz, mask+1) || (*psz && WildcardMatch(psz+1, mask));
                else if (*mask == '?') if (*psz == '\0') return 0;
                else if (*psz != *mask) return 0;
                psz++;
                mask++;
        }
}

What's the difference?

Do you have a reliable test-case for this, something that always fails on the first and never on the last?

Yes, test case(s) please?

Whatever this was, was my fault. I think.
