My first thought is to suspect the distro/source as I've still had no other equivalent reports and given the gdb spew. I'll have a dig further however as the GDB spew itself might actually be a useful clue. Not sure I can do much without a proper trace however (if gdb is borked on your box is strace giving sane reports ?) Alan
