I have a Mac with a Skylake processor and have also observed this problem.
I've been following this discussion a bit, but have recently been mostly

Reimer Behrends has helped me track down the explicit issue. We don't have
a patch yet, but the bug (and solution) is described here [1].
Basically the M4 macro JMPENT in mpn/x86_64/x86_64-defs.mac needs to do
more than just subtract the two addresses on Mac. However, I'm confused why
this isn'
It's certainly not a generic problem affecting Mac [0]. It's Skylake
specific and something their linker doesn't like that works on that
architecture on Linux.

Alex Best pointed out this morning that something similar came up for the
GMP guys a while back. Apparently something to do with jump tables. That is
probably affecting our code here [1].
We'll look into it. Unfortunately, in the mean time, the best one can
really do is delete the affected file

Surely MPIR guys would appreciate feedback.
This might be their assembler bug.

You're probably right as I have managed to rebuild 8.0.beta4 from scratch.
I won't attempt to build for a while:)

No 8.0.beta4 had an older version of mpir.

You appear to have some relatively recent hardware. I am suspecting
that the combination OS X + skylake cpu hasn’t had a lot of testing.
Not sure how to get around that really.
