This error only happened once so far, on the next branch. Is it related
to the bump of glibc 2.28 or is it also needed with older glibc
versions ?

I'm trying to figure out if this fix should be applied to the next
branch (where we have updated glibc to 2.28) or to master (where we
have glibc 2.27).

I would suspect it is related to glibc 2.28, otherwise the problem
would have already popped up on master. If that is the case, then the
commit log should say it's related to glibc 2.28.

Thanks,

Thomas
