Package: xterm Version: 244-1 Severity: normal Hi,
I just noticed that xterm doesn't like it very much to be resized: when I grab
a window edge and make a circular motion (i.e. enlarge and shrink again in
both dimensions), I usually get it to segfault within fractions of a second.
Here are a few backtrace samples...
