Thanks.

Since I don't have any ARM systems (the failure was in the central build) - I'd wait for the next release.

The next release of cglm was landed yesterday: https://github.com/recp/cglm/releases ☺️

[yurivict]

If the fix is included - I'd see if fallout messages would keep coming.

I was using a slighty older version of cglm and ran into this. Update the submodule to latest master and build works again. Thanks maintainers!

@recp There are no more failures on arm with 0.8.5.

@RobertLemmens @yurivict thanks 🚀
