There isn't much the GMP developers can do about compiler bugs. We
used to try to work around them, but the compiler bug bandwidth now

I actually suspect the set of correctly compiled non-trivial C
programs is approaching the empty set, over the set of compilers. A
workaround might thereby just start triggering bugs in another
Our current approach to compiler bugs is to boom out to users that
they should run "make check" and iterate over several compilers until
they get lucky. We trust the GMP test suite to catch any relevant
