Thanks for the report. I've spent some time trying to fix this but
haven't got it quite working yet. I found that the signal handler for
a resized screen could overwrite data while it's being used, so I've
been trying to block these signals while accessing this data in the
rest of the program. I haven't read your blog post in any detail yet
but I think this is the reason for all the uninitialized values/memory
corruption. I'll comment more later.

(If you want to see a related bug, try splitting the window with C-x 2
and resizing the window to be smaller.)
