--- Additional Comments From pinskia at gcc dot gnu dot org 2005-03-26 18:22 --- For the first problem with code generation issue, does -fno-strict-aliasing helps? For the second problem with respect with the ICE, well only -O1 -fschedule-insns -funit-at-a-time is needed to reproduce the problem. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20634

--- Additional Comments From halcy0n at gentoo dot org 2005-03-26 21:09 --- (In reply to comment #3) For the first problem with code generation issue, does -fno-strict-aliasing helps? No, same problem still. Only adding -fno-unit-at-a-time fixes the issue. I should add that it works fine with gcc 3.4 and -funit-at-a-time. For the second problem with respect with the ICE, well only -O1 -fschedule-insns -funit-at-a-time is needed to reproduce the problem. Yes, I get the ICE with only these options. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20634
