I do think it is related to GMP. When I stepped through the code via GDB, the segfault occurs when mpz_set_d is invoked. It didn't step into the function call/segfaulted on the invocation.

Then I cannot reproduce this here.

Thank you.

Given that the problem goes away for you if you completely remove the
calls to functions from the GMP library, my guess so far would be that
this is some bug in the version of GMP you are using.

Can someone else who uses a 64-bit build of Emacs 31 on Windows
reproduce this? If so, what version of GMP is being used?
