Dependency violation in parallel build (3.82, regression)

Using the attached Makefile, I get the following result:

% rm -f foo; make -j
start foo

So the qux recipe is run before foo is finished (or even started),
although qux depends on foo. The $(shell) calls as well as
.SECONDARY and the seemingly unrelated bar rules all seem to be
necessary to trigger the bug.

This is reproducible with 3.82. It does not seem to occur with 3.81.

BTW, I wanted to check against the current repository version, but
when I tried to fetch it as described on
https://savannah.gnu.org/git/?group=make, I got:

% git clone git://git.savannah.gnu.org/make.git
Cloning into make...
warning: You appear to have cloned an empty repository.
