--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
I expect that genops.c needs __libc_atexit to flush stdio streams in the
statically linked case.  We could likely handle this differently, e.g. call=
 a
weak function symbol in the process shutdown sequence if it is defined.

At present, the weak symbol wouldn't matter because we have a sequence vSDO
lookup =E2=86=92 dynamic linker =E2=86=92 malloc =E2=86=92 vfprintf =E2=86=
=92 libio which pulls in most of
libio anyway.
