On what machine? I've seen this mostly on SGIs and mostly when my
code has teleported the instruction pointer out into hyperspace and/or
badly trashed the stack. It can occasionally also happen when both -O
and -g are turned on in gcc, but usually something ugly has happened
as well.
About the only things I can suggest are to turn off any optimization
(if it's turned on) and to run the code from within the debugger with
breakpoints sprinkled liberally or by single stepping (using the
'next' function, where appropriate).
