Hi!
Alfredo: Jep, did that. GDB was how I figured out things went wrong
in FreqDisplayForm::setFFTSize() in the first place :).
Jörg: Interesting; but the error is quite reproducibly at the same
place; I'll try to set a breakpoint at the kernel call and see if
that happens again. But that will require some gdb magic (so that
GDB only interrupts program flow when the fft size changes), and
that's definitively something that would be worthwhile to learn,
however I'm postponing this for now for reasons of time available.
Greetings,
Marcus

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

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