Yay, this patch works for me! zsh-static built on Debian Unstable
(glibc 2.32) no more segfaults when copied to and executed on Debian
11 Bullseye (glibc 2.31) for me. (Just my way to test it, the issue
popped up in Debian Unstable the other way round when glibc was
upgraded from 2.31 to 2.32.)

Bart: Sorry for not providing a gdb backtrace in time. Was too tired
last night to figure out where to put Debian's debug symbols when not
installing the built packages (or to set up a fitting chroot for
testing with the built packages) for generating a backtrace with gdb.

		Kind regards, Axel
