Re: Gdb crashing or not attaching in Netbeans

["erupter at libero dot it" <erupter at libero dot it>]

  Finally I got logs!
I'm asking for help in understanding what is happening.
First is a correct log, as to say a log of a working debugging session up to 
the first break point.
Then a log of a crashed debugging session, from which the debugger never 
recovers (closing the IDE, restarting the computer, nothing solves the debugger 
crash. Just clearing the IDE user settings folder).

So here is a working log.

This is all being done automatically by Netbeans IDE.
When this happens, I have a "crash notification" from the System notification 
helper too.
