If I had seen yours earlier, mine would've taken a lot shorter ;-) See

Hi Gaby, 

Ah, I just submitted a bug report that dies in the same place. Please see
my post to see the gdb backtrace and cause of the crash.

The culprit seems to be 
  tree part_type = TREE_TYPE (TREE_TYPE (decl));
in function.c:put_var_into_stack().

Mumit
