I am running and testing the latest lxterminal trunk version,
$ svn info lxterminal/
Path: lxterminal
URL: http://lxde.svn.sourceforge.net/svnroot/lxde/trunk/lxterminal
Repository Root: http://lxde.svn.sourceforge.net/svnroot/lxde
Repository UUID: 3baf7735-d320-0410-8b56-b11ef3703fae
Revision: 2182
Node Kind: directory
Schedule: normal
Last Changed Author: majkl82
Last Changed Rev: 2182
Last Changed Date: 2009-12-10 01:35:16 +0800 (Thu, 10 Dec 2009)
the lxterminal will eventually crash with SIGSEGV, Segmentation fault.
but reason is unknown, and reproducibility is also random, especially
when using Alt+number to switch tab, it will randomly crash, but before
crash need how many times of switching tab is also unknown,
only crashing happens when switching tab is determined, other conditions
seem randomly, it may need several hours, or several days;
Who met this before? or is someone already addressing this problem?
then I recompiled it with "-ggdb" and try to debug it, found it seemed happen
on term_switchtab (term=0x7dcb10) at lxterminal.c:209,
$ gdb lxterminal/src/lxterminal
(gdb) run
Starting program: /home/gektop/src/lxde-trunk/lxterminal/src/lxterminal

[... many hours later]
