Repeated Mac arm64 crashes of xdvi-xaw with "set_no_char: attempt to set character of unknown font, offset 42"

[Richard Koch]

John,

I'm not going to be much help debugging this. As an experiment, I tried a 120 page document of mine with lots of math and illustrations. It took a long time to get a crash this time. But eventually I did, and the following message appeared in Terminal:

XDvi 22.87.04 (Xaw toolkit): Failed assertion:
../../../texk/xdvik/dvi-draw.c:2187: "color_bot_size > 0": color_bot_size mustn't become negative!
Aborting now. Please report this as a bug to:
http://sourceforge.net/tracker/?group_id=23164&atid=377580

This on an Arm machine, but I don't believe Arm is related to the bug.

Dick
