maybe provoking PR36450 although this one is about a slightly different thing
AFAICS?

I'm curious if you can build your distro with -O3 and -Os ?

Thanks for decreasing the test case.  The problem was in wrong mode of
save/restore stack slot when it was reused for another hard register.  It
resulted in generation of wrong save/restore insn and after that in a wrong
secondary reload insn needed for this insn and the last insn caused a crash in
the postreload pass.

The patch solving the problem will follow soon.
