Just so - when trying to execute built executable or debug it the debugger freezes. In process list is declared as running. Here is what I have done:

When building, the Messages window was opened. It would not switch to the GDB window.

If I switched to GDB window prior to start/debug program, everything would be OK.

here is the fallen process backtrace:
