--- Comment #2 from dj at redhat dot com <dj at redhat dot com> ---
It looks like changing "s =3D=3D 0" to "s < SMALLBIN_WIDTH" in the set_max_=
fast()
macro (around line 1622 in malloc/malloc.c) ensures that global_max_fast is
never set to zero.  This fix should apply and work for all current glibc
versions.
