I'm attempting to port a project that uses fmt to ubuntu 18.04/arm-64 on a Nvidia Tegra TX2 platform.

I'm not sure if I'm seeing a platform dependent issue, or a actual bug, but when running make test it gets stuck in a infinite loop. I'm stuck on ubuntu 18.04, as that's the only platform NVidia supports for their CUDA components, so I cannot change it.

I'm on current HEAD. (e7f31f5)

Including a lot of info since I'm not sure what's important here

Looking around, it seems like the format-test step corresponds to the format-test binary. Running it manually produces a number of failures before it gets wedged:

So it looks like /something/ is going pretty seriously wrong.

Resuming it and interrupting it several times seems to show it getting stuck at the exact same position every time, so it's wedged up in a very tight loop.

I'm running a debug build right now, though the tegra is not exactly a fun platform to work on (slooooow).

Ok, so the debug build doesn't infinite-loop, but it also fails:

Ok, I downloaded the 8.1.1 release tarball, and it passes all the tests, so whatever is broken is a recent change.

Note that the same build script passes its tests on x86-64 Ubuntu 18.04, so this is at least somewhat platform specific.

This is the same as #2810 which will be fixed shortly.
