I haven’t heard of this and I don’t think you’re right. Glibc, for all its faults, as a general rule does backward compatibility well. The problem is if you compile against a newer glibc (common in CI by default) and try to run on a distro with an older (common in the wild). If your CI uses an older glibc you should be fine AFAIK.

https://bugzilla.redhat.com/show_bug.cgi?id=638477 is the most "famous" example.

There are also much less well-known "little things" that regularly pop up here and there.

In any case, my binaries work not only under glibc, but also under Alpine, and (work in progress) under android/bionic.

		Not sure what you’re trying to show with that bug report but it’s not a case of cross distro glibc issues. If I read correctly it’s a vanilla behavioral change that exposed preexisting UB in flash. Not sure how the comments about alpine or bionic relate either to my claim that cross distro glibc is fine.
