Tell me what you need. The bug doesn't make gmp crash, so I don't have
a crash backtrace, but I can provide part of the backtrace of polly
hanging with the problem:

Don't know what else I can provide, I don't use GMP directly and don't
know how to use it even, so sorry if I can't provide enough
information by myself, but just tell me what you could be of use to
you and I'll try whatever I can to provide it.
