New comment by ericonr on void-packages repository https://github.com/void-linux/void-packages/issues/18659#issuecomment-773759024 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.
