--- Comment #2 from Dennis Cote ---
Ah, I see. So the default does no optimization at all, not even redundant
instruction elimination. Even -O1 completely inlines the function to 3 MOV
instructions with constant values. So I have learned to alway

I was premature in reporting that version 3.4.2 fixed this bug. I didn't get a
ICE on my test file anymore, but not because the bug was fixed. It turns out
that version 3.4.2 compilers ignore the -mrenesas t

This bug can probably be closed now. Good job.

This bug is triggered by calls to functions that return a char value combined
with the -mrenesas compiler option. Removing the compiler option, or changing
the functions return type to int will both eliminate the
