I've seen these too, I don't think that's related. I've also seen the
gcc ( or other binary ) crashes 'stick' - as in, crashing again in
exactly the same way until rebooted of flushed out of the file cache.

If you have any core files sitting around, you'll see the crash
happening in a long list of li ...; addi ...; followed by some sort of
branch instruction(s) if it's the problem I tried to fix.

That said, I had all sorts of weird problems with gcc 5.3, not just on
powerpc.

have fun
