gcc.c-torture/compile/20010408-1.c was the test case that the stack trace was from. That test failed on IA64 HP-UX with just the -O3 option. It looks like that passes in 64 bit mode though (-mlp64) so that is probably why it also doesn't fail on Linux. It looks like the failures on IA64 Linux require -g or -fomit-frame-pointer in addition to -O3 in order to have the failure. So for example, gcc.c-torture/execute/20020402-3.c, fails on IA64 Linux with -O3 -fomit-frame-pointer or with -O3 -g. Steve Ellcey s...@cup.hp.com
