It looks like we need to build GMP for older CPUs.
According to your last crash report, you're running a Core i7-3720QM and crashed in mpn_submul_1. GMP's "Build Options" documentation at https://gmplib.org/manual/Build-Options.html says that it can be optimized for a number of CPUs, and that its configure script defaults to "this CPU here, right here in my office". For the macOS builder that's a Core i7-8700B
The "Notes for Package Builds" section of the documentation recommends "--enable-fat" when shipping binary packages, which builds a range of optimized code and chooses the fastest at run time: https://gmplib.org/manual/Notes-for-Package-Builds.html
Homebrew defines an "oldest supported CPU", which appears to be "core2" and builds for that:
https://github.com/Homebrew/homebrew-core/blob/master/Formula/gmp.rb
https://github.com/Homebrew/brew/blob/master/Library/Homebrew/hardware.rb
...so, should be build GMP for everything or a single, older CPU?
