--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
There is no way we can help you debug this code with just a code segment.

Maybe you have a buffer overflow on the stack which is causing ArgMappers to
become null after the fprintf.
gdb and watch points are useful to see when the value of ArgMappers changes if
at all.
