[COMMITTED 2.24 / 2.25 / 2.26 / 2.27 / 2.28] Fix segfault in maybe_script_execute.

[Stefan Liebler <stli at linux dot ibm dot com>]

Hi,

I've cherry picked the commit "Fix segfault in maybe_script_execute." 
(https://sourceware.org/git/?p=glibc.git;a=commit;h=28669f86f6780a18daca264f32d66b1428c9c6f1) 
and it is now available on glibc release branches 2.24 ... 2.28.

Bye
Stefan
