Re: Xemacs dumps core on XMapRaised (PR#1461)

I'm using Xemacs on Accelerated-X 5.0 with 2 screen mode and the window manager is twm. Cursor are moved between the screens with f.iconify and f.deiconify (twm function). When I move the cursor between the screens, xemacs dumps core 4-5 per day. The following is the backtraced result of the core. -------- backtraced result #0 0x2829ad04 in _XtIsSubclassOf () from /usr/X11R6/lib/libXt.so.6 #1 0x281d3847 in _XawImGetShellHeight () from /usr/X11R6/lib/libXaw.so.6 #2 0x281cf4b2 in XawVendorShellExtResize () from /usr/X11R6/lib/libXaw.so.6 #3 0x281cf522 in XawVendorStructureNotifyHandler () from /usr/X11R6/lib/libXaw.so.6 #4 0x28295e32 in XtDispatchEventToWidget () from /usr/X11R6/lib/libXt.so.6 #5 0x282965e7 in _XtDefaultDispatcher () from /usr/X11R6/lib/libXt.so.6 #6 0x28296918 in XtDispatchEvent () from /usr/X11R6/lib/libXt.so.6 #7 0x2829f509 in XtAppProcessEvent () from /usr/X11R6/lib/libXt.so.6 #8 0x812da1e in alarm () #9 0x80a876b in XMapRaised () #10 0x80aa0ae in XMapRaised () #11 0x80aa42f in XMapRaised () #12 0x8063512 in XMapRaised () #13 0x8063387 in XMapRaised () #14 0x80794dc in XMapRaised () #15 0x8062eeb in XMapRaised () #16 0x8062f0f in XMapRaised () #17 0x80791f4 in XMapRaised () #18 0x80630a0 in XMapRaised () #19 0x807649f in XMapRaised () #20 0x8076b42 in XMapRaised () #21 0x804f049 in XMapRaised ()
