Hi Thomas,
This one is hard to reproduce (here). valgrind is not showing me any
problems as I resize the screen in various ways.
There are several special cases in the resizing logic, depending on
resource-settings, as well as the amount of text that has been scrolled
off onto the saved-lines buffer.
More details would be helpful...
while Julien has uploaded a new xterm package with fifo-lines disabled,
I can still help debugging the actual problem if this is desired. I
can reliably reproduce the problem with an empty (i.e. freshly started)
xterm with a bare prompt - once the buffer is full I can no longer make
it crash. My .Xresources only contains modifications to the font settings.
I'll do a few valgrind runs myself and report back.
The positioning problem is mostly a logic error (incorrect bounds
checking) around the call to saveEditBufLines in screen.c; which I think I
understand. Once I have a fix for that, I'm interested to see if applying
_that_ fix makes this problem go away.
