Package: make
Version: 4.1-9
Severity: important

Dear Maintainer,

running the attached Makefile will hang the process,
if multiple jobs are used then the process wont respond to a
TERM and has to be killed.

The very same issue is observed with make-guile.

I believe this to not be an upstream bug, since I observed this
only a couple weeks ago after an upgrade.
Unfortunatly I can`t pinpoint a date or version.

Kind Regards, Norbert

$(addprefix subdir/,$(FILE)):
        echo "$@"
        mkdir -p $(dir $@); touch $@
