[crash] 21.2-b8, linux, RH5.2, XFree 3.3.3.1
I finally got around to rebuilding with error-checking and debugging
enabled about 3 days ago. This is the first failure I've seen since
then. I kept the core, if there is more that should be dug up from it.
Program received signal SIGSEGV, Segmentation fault.
