Which is *not* what we asked for.
Please follow the instructions in doc/bugs. It gives DETAILED instructions on what to post. You are NOT posting the information we need to be able to help you.
You're just showing that you can run gdb. This isn't useful. You need to run the gdb commands in doc/bugs, which tell us WHERE the problem occurred.
