What is testcpro.c trying to do?  Is there code in there that will
generate instructions for a coprocessor module that doesn't exist
on your target hardware, and can't be emulated by your kernel?

Maybe it does floating point?  If you compiled with a hard-float
toolchain and ran on a target without an FPU, under a kernel that
didn't have floating point emulation built in, one might see the
symptom you've described.
