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 the program crashes quite frequently after seconds to minutes of operation. Based on my layman's perspective it seems to be a memory leak in the vector block.
I tried many things over the last couple of days. Nothing seems to mitigate it. For example self.lock and self.unlock to lock the flowgraph before reading from the vector (results in flowgraph never starting back up, seems to be a whole different issue)... I tried using python copy.deepcopy to make a copy of the vector contents before using it but that didn't help eiehter. When the exception occurs, it seems to happen right after resetting the vector sink. My flowgraph doesn't run standalone and requires a number of other applications to function but I'll work on getting it up to github for review if that helps Gnuradio 3.7.11.1 on a CentOS VM (Linux 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux) BTW when the exception occurs on OSX the error is: Python(86100,0x70000eab9000) malloc: *** error for object 0x7f94bf9042b8: incorrect checksum for freed object - object was probably modified after being freed.
