On PPC (Mac G3 running Debian "Lenny") I get the "Unknown..." exception 
in the IDE but don't get an error in lhelp.

I see neither error on ARM (Debian "Squeeze"). However this is an 
armv5tejl as implemented by Qemu emulation, and it might not be as 
touchy on alignment issues as something like a genuine armv5tel or there 
might be better OS-level handling.
