This is a known bug#65070.  Unfortunately, we don't currently have
anyone with access to such a machine who could debug the relevant code
and tell what is wrong with it.  If you can run Emacs under GDB on
that machine and report some findings (I can provide more detailed
instructions), we might be able to fix this.
