I've run into other cases, with assembly language code in kernels.  It
may be that this could be cured by throwing in more magic assembly
language pseudo-ops.  Then again, I have a modified GDB that usees
prologue analysis to handle not just function calls, but also
interrupts and exceptions; this is quite handy in RTOS work.
