Before I start debugging, does this ring any bells?
Yes, this is the same failure on powerpc-darwin.
<http://gcc.gnu.org/ml/gcc-regression/2005-06/msg00090.html>.
It is also the same failure as I reported in
<http://gcc.gnu.org/ml/gcc/2005-05/msg01362.html> when I disabled
forwprop
and the preprocessed source still is able to reproduce it with todays
clean source.
