I should have fixed that in revision #5992 for gb.pcre.

The warning message is printed when the "length" argument of 
GB.ReturnNewString() is lower or equal than zero, because it won't 
return a null string but compute the string length with strlen() (this 
is a backward-compatibility with older versions of the interpreter API).

If you want to return a void string, use GB.ReturnVoidString() as I did 
in gb.pcre.

If you are using the old syntax of GB.ReturnNewString(), use 
GB.ReturnNewZeroString() instead.
