And what is $(VERSION_TXT)?  Can you show the contents of that file
here?  Also, what is the shell used by Make on your system?

FWIW, I cannot reproduce this with the following minimal Makefile:

VERSION_TXT = version.txt
VERSION_STRING = $(shell cat $(VERSION_TXT))

all:
        echo $(VERSION_STRING)

However, my cat.exe is from GnuWin32 site, not from unxutils.  I'm not
sure if this matters.  I tried the above Makefile both with a native
Windows port of zsh and with SHELL=cmd.exe, which causes Make 3.81 to
invoke CMD.  Make didn't crash in either case.

Thanks for the analysis, I will look into this.
