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.

That bug report was a good read.
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.
