Description Ciaran McCreesh 2006-10-20 04:07:08 UTC

xterm-220 segfaults on echo -e '\e]12;red\x7', and by extension when using various fancy Vim features. Backtrace:

(gdb) run
Starting program: /usr/bin/xterm 
Warning: Cannot convert string "nil2" to type FontStruct

This is fixed in 222.

Removed xterm-220 and xterm-221. xterm-218 will remain the stable one for now, on all architectures.  xterm-222 will become a stable candidate in about a month -- it does not display this issue.

nice catch.
