It started to ICE on the tree-ssa:
: Search converges between 2003-08-31-ssa (#74) and 2003-09-01-ssa (#75).
But it stopped:
: Search converges between 2003-09-01-ssa (#75) and 2003-09-03-ssa (#76).
At which point we started to produce wrong code.

This looks like a laten bug in the rtl optimizaters.

Note with -O2 -fno-gcse I cannot reproduce this.
