level of memory reference.

This is probably a REG_OK_STRICT bug. During reload, an unallocated pseudo-reg is actually a memory reference in disguise, so you must check for and reject pseudo-regs during reload. This is handled by the REG_OK_STRICT macro. Just look at any port to see how to handle this correctly.
