There are various guides recommending noexec, however they warn that 
some issues should be expected.

Likely you mean

(process-file "/usr/bin/bash"
 "/tmp/babel-NfRG9P/sh-stdin-o3CEm5" #<buffer  *temp*> nil 
"/tmp/babel-NfRG9P/sh-script-jmKNA4")

but it would ignore shebang. Try

#!/bin/sh -e
false
printf "Should not be executed\n"

So it is necessary to either drop :shebang or set temporary directory to 
a suitable path.
