make 3.79: core dump expanding target specific variables

Consider this makefile:
t: m+=2
t:
@echo "[${m}]"
Then the following sort of works:
$ make t
[ 2]
$
(Interestingly, make 3.77 (which I have kept a copy of) produces a
different result:
$ make377 t
[2]
$
Hmmm.)
BUT the folowing crashes:
$ make m=hello t
assertion "current_variable_set_list->next != 0" failed: file "/cygnus/netrel/src/make-3.79.1-2/expand.c", line 489
0 [sig] make 1580 stackdump: Dumping stack trace to make.exe.stackdump
Aborted (core dumped)
$
All is OK with m:=hello on the command line (note the colon), and also
running with make377. None of make-3.79-3, make-3.79.1-1, or make 3.79.1-2
work.
