if the sim isn't stopping, i don't think it's correct to display anything at 
all.  it is valid to simulate code that purposefully makes bad/weird memory 
accesses and then recover at runtime using signal handlers.  uncommon perhaps, 
but not invalid.

for diagnostic info meant for the developer, putting it behind a debug/trace 
knob would make more sense.
