                 Summary: [Makefile:5: foobar] Segmentation fault
                 Project: make

                Severity: 3 - Normal

             Assigned to: None
             Open/Closed: Open
         Discussion Lock: Any
       Component Version: 4.2.1
        Operating System: None
           Fixed Release: None
           Triage Status: None



For this Makefile:

ROOT := ${shell echo
/home/mgaleck/ws/mgaleck_build/mgaleck_build_refactor2/target | sed s/t/t/}
export LD_LIBRARY_PATH := ${ROOT}/usr/lib64:${LD_LIBRARY_PATH}

        touch $@

and file foobar missing, then on some Linux distributions, I get this:

$ make-4.2.1/make
touch foobar
make: *** [Makefile:5: foobar] Segmentation fault (core dumped)

The above Makefile is SSCCE for me - if I delete any elements from the above,
even just one letter from the echo string, does not happen.  

This happens on CentOS 7.3, but on latest Ubuntu, does not happen.  I am
hoping that this is merely a matter of different timing and the bug is really
present on all OS and a person sufficiently familiar with the code can see it
from the above description.
