Thank you for the test case, I could reproduce the crash.

Attached patch fixes the romcc segfaults when using the |=, +=, ^=
operators on array fields and produces reasonably looking code.

I did some tests to verify that the behaviour didn't change, but your
test case compiles to no code (except some useless jmp instructions) as
it has no side effects, so I can only verify it builds.
Please test it on your real world code.
