#260 sdcc - crash when compiling faulty code

[Peter Dons Tychsen]

Hello SDCC team,

Here is a small crash i found. It happens when compiling the following:

void x(unsigned char *y)
{
  unsigned char a;
  y[0] = 2;

  return 1;
}

Flags: -mstm8 --debug --out-fmt-elf -c main.c -o main.rel

The reason is that the dwarf2 outputter cannot handle incomplete generated data.

The easy fix is to just not process the dwarf output if there is a fatal error. There is no need for it anyway as there are no output files when a fatal error occurs.

The patch adds a check for this fixing the problem.

Thanks,

/pedro

Just for the record this is an ICE not a real crash if you where wondering... :-)
