Comment:
This is because `libstdc++` sucks a bit on non-glibc, where it assumes no locale besides the `"C"` are supported.

Thanks for bringing other failing applications to our attention... Ideally, they would do like `snapper` does: #5212, where it only complains. We can consider including a patch that disables the exception, but it's a bit misleading, unfortunately. I would like to get this solved on the libstdc++ side, but it is a lot of work.

Comment:
PrusaSlicer has the same problem and workaround on x86_64-musl as well:
```
An error occured while setting up locale.
You may need to reconfigure the missing locales, likely by running the "locale-gen" and "dpkg-reconfigure locales" commands.
PrusaSlicer will now terminate.
