Are the ICEs in bugzilla?
Runtime faults need to be distilled into a testcase, and Bero said KDE
compiled with -fomit-frame-pointer works just fine for him, so somebody else
has to submit a testcase. But ICEs are easy to test and not hard to debug
(usually).
But -fschedule-insns will not work properly with any gcc out there on IA-32,
it is just luck that your particular code does not ICE with particular version of
compiler.
