coredump. dbx shows gtk internal functions.

[Mohan Kumar S <mohankumar sekhar alcatel com>]

coredump. dbx shows gtk internal functions. i cant figure out where &
why it happens.Please help

Hii,

I am runnign a multithreaded gtk program, i have followed all the
guidlince for gtk+ with multithreading

gdk_enter(), gdk_leave(). etc

The program does coredump, which is not reprodusable.

Its a multithreaded program, with main thread, taking care of lots of
gui, the secondary threads ,taking care of creating tcp sockets &  using
the gui occasinally to display the messages comming through the tcp
connection.

when i debug using dbx, "where"
the most frequent one is this

g_type_check_instance

can anyone please tell, where there could be a problem

(dbx)where

another frequent  coredump happens when the execution is inside main.

at
main(  (int argc, char *argv[])
{
..
...
...
gdk_threads_enter ();
  gtk_main ();
  gdk_threads_leave ();

  return 0;
}
