================================================================ Dear Bug Team! I regularly get a regex.c assert core from XEmacs running Gnus any time it encounters an arriving mail (spam) message using MIME-encoded charset GB2312. The dump is an ABORT() on failing to find a valid syntax opcode type; reproducible on demand. If needed, you can find a saved core file and the victim spam that induces crash at http://www.charcoal.com/~karl/xemacs.crash/ (102Mbytes). Fedora Core 4.
