Hi XSF!
Running xterm under valgrind shows heaps of errors after resizing the
xterm to one line height:
==8438== Invalid read of size 4

==8438== Address 0x1BFFF470 is 739680 bytes inside a block of size 754560 free'd
and much more of this. Please, could someone with a debug-enabled xterm look
into this?
This leads to a reproducible stacksmashing SEGV when running scp within
this xterm.
