Subject: | [Discuss-gnuradio] Assertion Failure in gr::buffer |
Date: | Mon, 22 Sep 2014 10:44:33 +0100 |
All, I am running a basic PSK Mod block in one GRC flowgraph and another flowgraph with a basic PSK Demod. I am using two URSP N210s, one as transmit, one as receive and GNU Radio 3.7.5, built on Ubuntu with Debugging Symbols. If I start the PSK Mod, while the Demod flowgraph is running, I get assertion failures. The following is printed in the ‘top_block’ Python output window: This early on: (python:3210): Gtk-CRITICAL **: IA__gtk_progress_set_percentage: assertion 'percentage >= 0 && percentage <= 1.0' failed And this later on: python: /home/luke/gnuradio-3.7.5/gnuradio-runtime/include/gnuradio/buffer.h:170: unsigned int gr::buffer::index_add(unsigned int, unsigned int): Assertion `s < d_bufsize' failed. Which then causes (in the GDB output): Program received signal SIGABRT, Aborted. 0xb76f4424 in __kernel_vsyscall () Does anyone have any idea where to start with this? Or can anyone reproduce the same problem? Thanks, Luke |
