Why the bus error? What am I doing wrong?
While I don't understand why you're getting a bus error (haven't
looked at the library source), the problem appears to go away if you
declare ctx as a global instead of on the stack. Perhaps
getcontext() just won't let you save context onto the stack....
Looking at it in gdb, the problem seems to be when you return from
main, not during the getcontext() call.
