           Summary: Ash segfaults when file does not exist

        OS/Version: Linux

We use this construct to read a file:

echo $(</tmp/file)

Now, if this file doesn't exist, busybox ash as found in 1.15.3 and 1.16.0
segfaults. 1.14.3 ash and bash both do the right thing, which is 

bash-3.2$ $(</tmp/non)
bash: /tmp/non: No such file or directory
