I still cannot use a debugger on this system, but I have collected two
more backtraces from emacs built with the same options as before, from
changeset 65ac27783a959a8339c2aab0f1e54d9b508a1f1f on master.

In both of these I was typing in an rnc-mode buffer (for a Relax-NG
schema), and it crashed while I typed OSVERSION as an element name in
the schema (only the O was displayed). The file is plain ascii.
