Details:
With this Makefile on my Darwin system (MacOS Mojave 18.7.0), make-4.2.91
loops indefinitely and i have to kill -9 (kill -15 is not enough):
% cat Makefile
target:
echo anything
non_existent_program
% make
anything
non_existent_program
make: non_existent_program: No such file or directory
make: *** [Makefile;3: target] Error 127
Killed
%
This is also the case with make-4.2.90 but not with make-4.2.1.
Commenting out the line "echo anything" has the same effect (endless loop),
but completely removing this line makes the hang disappear (and 'make' to work
correctly).
Using --disable-posix-spawn also makes the hang disappear in all situations
(it seems).
Regards,
Denis Excoffier.
