I've actually had nasty crash bugs using -xO3 -xspace -xilfoff on perl 5.8.5 on amd64 (-xarch=amd64) -- using Sun's compiler, of course. It would perfectly for our i386 builds, but seems to touch some bugs on amd64. I've had to drop back to simple "-xO2" to get it to pass our test suite. As a note to those who care. We run into so many compiler "over optimization bugs" from various compilers that we don't regularly report them any more. The worst offender, by far, is the Visual Studio .NET compiler. But, each has its own quirks.
