I don't know if it's supported to do this, but I'm crashing VIm70g,
WinXP by doing a "new" in a "TabEnter" autocommand. The crash doesn't
immediately follow the "new" command, but soon after when other
functions start looking through the windows.
I can't get a crash in a test case, but if you run the script below,
and if you :tabnext 5-10 times, you can see it getting real
confused about the windows (i.e. can't :wincmd w to some of them,
can't quit some of them).
I've included a gdb backtrace from Vim70g03. It looks like the window
list variables have been broken in eval.c.
P.S. What I'm trying to do is open a window
conditionally/automatically when entering a tab. Is there a better
way other than TabEnter?
