[edit] Whoops, that's not right...
I think I need to add that the error message is a little misleading:

Quote:libstdc++
if (__builtin_expect(__is_null_pointer(__beg) && __beg != __end, 0))
  __throw_logic_error(__N("basic_string::_S_construct NULL not valid"));

So it will complain about NULL even if the char array is just empty ("\0").

Glad you fixed the problem.

oops my bad that wasn't the problem.
the real problem that was causing the thing was this:

getenv("QUERY_STRING")

so if there is no query string passed through the cgi, the returns a NULL.
Before:

	if ( s == "&"  ){		if ( !ParseGet( getenv("QUERY_STRING") ) )			return Failure;	}

After:

	if ( s == "&" && getenv("QUERY_STRING") != NULL ){		if ( !ParseGet( getenv("QUERY_STRING") ) )			return Failure;	}

Difference:
getenv("QUERY_STRING") != NULL


So yea. That was the REAL reason.
