[sdcc-devel]bug report: compiler crash in geniCodeParms

[Johan K. <joh...@id...>]

extern unsigned char docrc8(int, unsigned char);

unsigned char tstcrc(int portnum) {
  unsigned int lastcrc8;

  lastcrc8 = docrc8(portnum,'a');
  return lastcrc8;
}

(changing lastcrc8 to a char avoids the crash, but that's not the point)

Because operandFromSymbol() is called with a "parm->argSYM==0" argument.
I think the test at SDCCicode.c:2702 is too strict, but I don't know how to
fix it.

Please help,
Regards, Johan
