Segfault crash when changing frequency-correction #2

Open Dieter9 opened 3 years ago

Dieter9 commented 3 years ago

I am using gr-osmosdr with my SDRplay RSP1A and Gqrx Software. Things are going very well, with one exception: When Gqrx is started and the device is running, I can change the frequency-correction as I like. But when the device is not running and I change this value, gqrx crashes with segfault. The problem is, if the frequency-correction is added to the Gqrx configuration file, this will happen every time Gqrx is started. :(

The system-dump points to a problem in libgnuradio-osmosdr.so - sdrplay_source_c - set_freq_corr :

Maybe it is possible to find a solution for this.

I am having the seg fault using gr-osmosdr with my SDRplay RSP1A and Gqrx on a Raspberry Pi. It occurs when I change Freq correction without the DSP/SDR running and when I start gqrx with a freq correction value in place. See https://github.com/gqrx-sdr/gqrx/issues/1345
