Using egcs 1.0.2 prelease, it looks like egcs is messing up how it
pushes
arguements on the stack. In partiuclar, egcs should be filling all of
the integer
argument registers, r3-r10. Instead, it places what should to in r8 in
r10, and placing
what should be in r9 and r10 on the stack. This leave r8 and r9
completely random, plus
pushes the final two integer arguments (which should be on the stack) 8
bytes off from
their correct position.
Assuming that fprintf correctly interprets the format string, it is no
wonder that
it crashes.
