Calling a function with 14 parameters in QML leads to a SEGFAULT

      When I call a function with 14 parameters in QML I get a segfault in:

      qv4stackframe_p.h line 190:

      memset(jsFrame->args + argc, 0, (nRegisters - argc)*sizeof(Value));

      nRegisters is 11 and argc is 14, so the third parameters yields -3*sizeof(Value) which is converted to size_t.

      I guess the memset should only be done in case argc<nRegisters?
