VETO
Start with xemacs -vanilla, C-h f rassoc RET, bye-bye XEmacs!
Repeatable. Revert the patch, no crash.
By the way, there are changes in src/symbols.c and src/sysfile.h that
aren't in the ChangeLog. I assume these are due to your commit.

Warning:
Defaulting to the GNU Emacs-derived `sendmail.el' mail client. This facility,
while part of base XEmacs, is heinously underfeatured, and not going to get
better in the medium term. We include it so that bug reports work without
packages; we suggest that you choose and/or install one of the other mail
clients from packages if you're doing something other than M-x
report-xemacs-bug , or even if you are reporting bugs regularly.
To choose a package from those installed, click on "Options" ->
"Internet" -> "Compose Mail With ..." and decide on one from the
list. Gnus and VM are full-featured and have active user communities.
To disable this warning and stick with the old behavior, you can explicitly
initialize `mail-user-agent' to 'sendmail-user-agent .

Info: Undefined Unicode key mappings.
Your keyboard has, among many others, the following keysyms defined:
U203A UFB02 U25CA UFB01 UF8FF U2039 U2044 U02C6 U0003 U02DC U2206
The standards say that applications should interpret these keysyms as
representing the corresponding Unicode code points (e.g. U2720 should
represent MALTESE CROSS), but unfortunately the current version of XEmacs
has no support for many of those characters in its internal encoding, and
when it encounters the keysyms corresponding to those characters, they
remain unbound.
See the documentation for `unicode-to-char' for one technique if you have an
urgent need for support for one of those characters--you probably don't,
most of the widely-used characters have mappings in the internal XEmacs
encoding--otherwise, wait until we ship a version with an internal encoding
based on Unicode.
