I couldn't get this code to run anywhere, so I haven't been able to
investigate your report properly, but...

util.c:Perl_my_fflush_all() should take care of this, and it is called,
via PERL_FLUSHALL_FOR_CHILD, in all the obvious places. Does that fail
to work correctly on your system, or is not called at all?
