I'll do my best, but it might take me quite some time to get gdb set up
with the symbols you mentioned. C++/debugging doesn't come naturally for
me.
What it smells like to me is memory is being freed but then written to.
Then when the system goes to allocate memory it says hey that memory isn't
Hi Brad,
Sorry that I missed your mail for so long!
So, I'm pretty certain I've fixed a potential race condition when
accessing the data vector in vector sink lately:
https://github.com/gnuradio/gnuradio/pull/1445
But that should be included in the 3.7.11.1 release you're using... hm.
We
Ah, by the way, the function names where that error occurs are mangled
C++ names; I'll try to show what is what (using `c++filt` to demangle
the names)

OK, that's malloc; are we certain that this
The Vector Sink is coming in very handy for some experimentation I'm doing.
I'm analyzing the output of an FFT block which terminates into a float
vector sink. every few seconds from a thread which then calls reset() to
clear the contents in preparation for another read. This seems problematic
as

Thanks, I realized what I need to do. Next monday I can try it, probably it
will solve the problem.

You can use gr.probe_signal_vc to grab a vector

I can't tell what your problem might be without seeing your entire script.
A minimal script doing something like this is:
from gnuradio import gr
tb = gr.top_block()
src = gr.vector_source_f([1,2,3,4,5,6])

Greetings,
I would like to ask you how to read the data stored in a vector sink. I tried
the solutions I found in the discussion list. You can see some part of my
python code below.

What's the intended usage for a Vector Sink? I have the output vector

pick out specfic subsets of bins, and do stuff with them.

The vector sinks are not meant for production code, but for simple
tests scripts. If you need to continuously get data out of a flow
graph, the best approach is to use a message sink and have a thread
that reads the message queue until another message is posted, then you
do what you want
