Dear Bug Team! XEmacs 21.5-b6 crashed with an assert. I was using it to read mail under VM, and garbage collection was going on. I've included the stack trace and the lisp stack trace... Lisp backtrace follows: # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (condition-case ... . error) # (catch top-level ...)
