I'm talking about this code:

----8<-----------------------------------------------------------------

BEGIN_METHOD(CREGEXP_new, GB_STRING subject; GB_STRING pattern; GB_INTEGER 
coptions; GB_INTEGER eoptions)

     int errptr;
     const char *errstr;
     int *ovector;
     pcre *code;
     int copts;
     int eopts;

// BEGIN source of random crashes

     THIS->subject = GB.ToZeroString(ARG(subject));
     /* Benoit, the reason we need to keep the subject string around 
	is because pcre returns each match using an offset into the 
	original subject and a length, not as a string! -RK */

     THIS->pattern = GB.ToZeroString(ARG(pattern));

// END source of random crashes
