commit f5ec0ea9eaf9753188a0bfa391b101ea8d5efc2b

    posix: Fix segfault in maybe_script_execute
    
    This patch is essentially 28669f86f6 adjusted for the generic
    implementation.
    
    Checked on x86_64-linux-gnu with Linux spawni.c removed.  The only
    failure is posix/tst-spawn3, which is expected.
    
    	[BZ #23913]
    	* sysdeps/posix/spawni.c (maybe_script_execute):
    	Increment size of new_argv by one.
