Hi Brian,

You try to execute a CP1 instruction in a delay slot,
which triggers a Reserved Instruction exception.
Per the ISA the processor operation is UNPREDICTABLE in such case.

What is the behavior on real hardware?
An assertion() seems appropriate.

Your compiler might be buggy, or you are not compiling for the correct CPU
(or you are not using the correct QEMU cpu).
