Please run cc1 under gdb and show us the "Illegal instruction".

> Please run cc1 under gdb and show us the "Illegal instruction".

I think the illegal instruction is caused by stack overflow:

gdb prev-gcc/cc1 gcc/cc1.core

Core was generated by `cc1'.
Program terminated with signal 4, Illegal instruction.
