I'm tracking an issue like that, causing the debuggee to run into a SIGBUS, due 
to the program counter being messed up somehow. AFAICT, this sometimes happens 
when stepping over code that migrates between primary and secondary modes (and 
rt_task_create does). I need to log this one on the bug tracker. It's pretty 
PITA to chase, but it's 100% reproductible here, so there's hope.
