These test suite failures smell compiler bug.  Unfortunately, while
Apple is a large company, their compiler team does not seem to be able
to produce a robust compiler.  Only every few "Xcode" release comes with
a compiler which GMP does not trip up.

I haven't kept a list of versions of the compiler which does not work.
But I know for a fact that the first Xcode release which came with
Catalina did not.  The first update was no better, but I think the third
update actually worked.

You might want to install a new Xcode version.
