I am using (or am trying to use) c::b under Linux (SuSE 10.0).
For sereral svn releases (more than 50) I observe the following behaviour. svr release is now 3615.
1) Startup: c::b toggles between:
a) hangs during startup, splash is visible. I have to kill/cancel c::b
b) starts an deletes the lock file (I allowed one instance of c::b only), then runs
I.e. starting c::b I get ...a) b) a) b) a) ....
2) Quit: Runs in a segmentation fault or does a pure virtual method call. This is logged on console (stderr?).
I am aware that all this is not very helpful to fix the problem(s). I ran c::b from gdb and post the log below. Maybe that helps a bit more in finding the bug. Perhaps you can tell me what I can do in addition in order to get more info to supply you with.
berlios.de is not available at present, so I post here.

Notes:
-- The DSO warning probably comes from gdb or ddd.
-- The SIGSEGV occurs after I exit c::b via File->Quit. I did not do anything with c::b except start it and quit it.
-- The SIGINT comes from the debugger (CTRL_C) after some time of c::b's freeze.
