bmake version:
└─[iblis_at_abeing]% make -r -f /dev/null -V MAKE_VERSION
20160818

Accutally, I made it core dump via a julia script.
Please checkout this code

└─[iblis_at_abeing ]% cat test.jl
makefile="""
CATEGORIES= devel

USES=
.include <bsd.port.mk>"""

cmd = `/usr/bin/make -f - -V MAKE_ENV`
in_ = Pipe()
out, proc = open(cmd, "r", in_)

print(in_, makefile)
close(in_)

_at_assert success(proc)
close(out)

└─[iblis_at_abeing]% MALLOC_CONF="junk:true" /usr/local/bin/julia test.jl
