Subject: Fatal error on resizing window
FCC: ~/.mail-archive
--text follows this line--
Emacs version: 18.55
Machine/OS: Sun 386i/SunOS 4.0.2, and also Sun SparcStation 1/SunOS 4.0.3c
To reproduce:
        % sunview
        % shelltool  -Wp    0   0 -Ws 1152 900 -WP  960 836 -Wb   0   0   0 -Wf 255 255 255 -no_name_stripe -Wg
        (in the shelltool window)
        % emacs -q
        (now use the mouse to grab one edge of the window, and resize
        it.  Shrink the window so that it's about as narrow as you can make
        it.)

I see `Fatal error (6).', and a core dump.
