Bash Version: 5.2
Patch Level: 2
Release Status: release

Description:
        I can no longer run xxx-ct-ng.config scripts produced by crosstool-ng.
        Those just contain a few lines of script, with appended bzip2 
compressed text.

        Bash 5.2 changed the check_binary_file function, it seems any NUL in 
the first
        80 characters will cause the error.

Repeat-By:
        Create a test.sh with :
        #!/bin/sh
        tail -n+4 "${0}" | bzcat
        exit 0

        $ echo foo | bzip2 >> test.sh
        $ bash ./test.sh
        ./test.sh: ./test.sh: cannot execute binary file
