bug in 21.5-b31 crash in redisplay.c similar to issue 697

I installed the latest beta XEmacs 21.5.31 and was testing toolbars and found a bug. I put on a bottom toolbar with only text glyphs in it, though otherwise identical to the default toolbar. When I clicked open button, find-file dialog comes up, then 3-4 seconds later XEmacs crashes and goes away. If I use the open button on the default toolbar, it works fine. I also noticed the bottom toolbar shows up on the find-file dialog before it crashes. Below is the lisp backtrace for XEmacs -vanilla, and attached are a C backtrace, and the code I ran to put the toolbar up. This works repeatedly, and was the same when running xemacs -vanilla. It is similar to issue 697, but triggered differently. Should I start another issue? Or put this in as a message under that issue? exact error message: Fatal error: assertion failed, file redisplay.c, line 9179, pos >= 0 && pos < dy->largest_ Fatal error (6). -------------------------------------------------------------------------------------------- Lisp backtrace follows: # (unwind-protect ...) event-window(#<motion-event 28, 701 0x10b5>) # bind (frame event) default-mouse-motion-handler(#<motion-event 28, 701 0x10b5>) ("execute_internal_event()" "[internal]") (dispatch-event "[internal]") # (condition-case ... . error) # (unwind-protect ...) read-minibuffer-internal("Find file: ") byte-code("..."
