I'm sorry, but I guess I need more help understanding gdb on a multi-threaded
program.  I ran backend from gdb, it kept stopping with signals SIG32, which
I found out how to stop with 'handle SIG32 noprint', so now it recorded 
several programs, then I got my SEGV, now its in the debugger, but a bt only 

(gdb) bt
#0  0x40aab10e in select () from /lib/i686/libc.so.6
#1  0x407fa730 in typeinfo for QMotifStyle () from 
#2  0x4035a090 in QApplication::enter_loop() () from 
#3  0x402ef32d in QApplication::exec() () from /usr/lib/qt3/lib/libqt-mt.so.3
#4  0x0805ff16 in main (argc=1, argv=0xfffffdfe) at main.cpp:223
#5  0x409fc082 in __libc_start_main () from /lib/i686/libc.so.6

    new MainServer(ismaster, port, statusport, &tvList);


    delete gContext;

I don't think very helpful.  I'm guessing gdb is pointing at a different 
thread, how do
I jump to the thread that died?
I'll leave the gdb open for a while if you can reply quickly...

Sorry to be such a pain?
