Actually you can “freeze” execution and spying every thread with gdb, or just let sereval of them continue as your wish . Use data breakpoint can trap the exact point where abnormal happens.

Keep in mind, with the multi-threaded scheduler you wouldn't end up in a deterministic state. Unless of course you only want to debug the state of your own block -- then you can do what WarMonkey suggested.

Is it possible to single step a flow graph?
I have a recorded stream of FSK modulated data with about 25 bursts of messages.
When this is later decoded I do not get 100% detection, about 4 of 25 bursts fails.
Now my thinking is can I play this burst by burst and see what is wrong.
So my plan was to stop the scheduler after each burst.
Can I control (stop) the scheduler when a 'tag' is detected and restart it with a GUI button.
Block,Python,C++ dosen't matter...
