The SIGILL signal handler doesn't return, it calls longjmp. If you're curious about all this stuff, feel free to ask questions; I'm quite familiar with these techniques. Again, please provide a backtrace that is useful. You can either get one from a core dump directly, or get one the way I described by ignoring SIGILLs that have oil_cpu_fault_check_try() in the backtrace. Using 'handle SIGLL nostop noprint' might be too heavy-handed for your preference, please use 'c' to continue after gdb traps SIGILLs that have oil_cpu_fault_check_try() in the backtrace. There *should* be only one (the initial Altivec check), but occasionally implementations get added (and released) that don't have OIL_IMPL_FLAG_ALTIVEC set, in which case liboil will print out an error message and disable the implementation. You may also wish to compile the source and run 'make check'. dave... -- David Schleef Big Kitten LLC (http://www.bigkitten.com/) -- data acquisition on Linux -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
