An update here. This is definitely a compiler bug on this platform.
Removing the default -funroll-loops default optimization option delays
compilation failure somewhat further, but still winds up with an
"Illegal instruction" (!) produced in the assembly. Even with just
-g, the xfindCE binary segfaults. I'll try to find time to file a bug
against the compiler, but it looks hopeless for atlas on PPC for now.
Perhaps I could try gcc 2.7.3, if it existed on PPC. Anyone have any
experience which might indicate that this would be worth a try? Or
any PPC users care to share an insight as to what compiler weakness is
most likely being touched on here?
Take care,
