[Bug bootstrap/20282] New: gcc4 can not bootstrap itself anymore

This is a all native powerpc64-linux build enviroment,
which itself is compiled with the current hammer-3_3-branch.

The script below fails in the last function call.
It does work if I compile a gcc-4.0.0-20040913 with itself.
A simple 'build_one_try gcc4-1  ~/src/gcc-head ; build_one_try gcc4-2  ~/src/gcc-head'
fails as well. A 'export CFLAGS=-O1' does not fix it.

Trying the snapshots between September and March now.
