#2443 SMT8 - crash in DWARF generator for empty main

[Peter Dons Tychsen]

Hello SDCC team,

Version: SVN trunk

There is a crash in the DWARF generator when using an empty main() like this:

main.c:

int main(void)
{
   return 0;
}

The DWARF generator crashes when the following is called:

sdcc -mstm8 -c main.c

The reason is that in "dwWriteEndFunction()" "dwFuncTag" is null because "dwWriteFunction()" is never called for "main".

I think "dwWriteFunction()" should have been called for "main", but i have not looked into how/where to change this.

Thanks,

/pedro

Ah sorry, the options are of course: sdcc --debug --out-fmt-elf -mstm8 -c main.c

Fixed in reversion #9429.
