[Bug: 21.4.17] font-lock-mode segfaults

================================================================ Dear Bug Team! I just upgraded my Opteron box to the latest Debian unstable, including an upgrade to Xorg xserver (6.8.2.dfsg.1-11) and a reinstall (from source) of the NVIDIA drivers. As it indicates below, I'm using xemacs 21.4.7. Since the upgrade, I get a segfault whenever I try to enable font-lock-mode. I don't have the sources installed at the moment, so a backtrace is probably not tremendously useful, but just in case: Program received signal SIGSEGV, Segmentation fault.
