Files to reproduce the crash

This segmentation fault is 100% repeatable for me in 30.1_3,3 on amd64 and also
in 30.1_2,3 on i386.  It worked in emacs-29.4.  The elc file was compiled with
an older version of emacs, but doesn't contain any actual byte code.

1. Unpack the attached tar file into some directory, e.g. /tmp/emacs-test

2. Run emacs -q -l /tmp/emacs-test/crash.el

It crashes like this:

Fatal error 11: Segmentation fault
