As Alexander says, you must first rule out hardware problems.  If it
turns out there is nothing wrong with your hardware, I'm intrigued by
the bus error you are getting.  Is there any change you can get a
backtrace on those crashes?  And obviously, which compiler are you
using, and which special CFLAGS, if any?
