Re: [Discuss-gnuradio] QT Gui FFT resizing Segfault

[Jan Krämer]

Hey,

I know another GSoC Student has problems with the a GT GUI sink as well. It would randomly SEGFAULT in a volk multiply kernel. I think it is the volk_32_fc_32f_multiply_32fc kernel used in waterfall_sink_X_impl::fft(). This kernel takes the FFT size as an input argument, so it could be related to your problem. I just had a quick glance at it so I am not sure though. I'll ask him to post his exact problem when he arrives at the lab. Maybe he can shed a bit more light on this problem

I hope someone more familiar with the qtgui infrastructure might chime in.

Hey Marcus,

Did you try debugging the SEGFAULT using gdb? This is a good reference to try:
