Alan Corey alancorey at yahoo.comThis is with a version of rtl-sdr I got by git last night and OpenBSD 5.2 (current release). 5.2 has some pthreads fixing so I waited until I bought another computer and loaded it. Are the crashes related to threads? I don't know, but possibly. It didn't work with OpenBSD 5.0 either. rtl_fm crashes and uses threads rtl_adsb crashes and uses threads rtl_tcp doesn't crash, uses threads, actually stops on ctrl-c rtl_test doesn't crash, doesn't use threads, won't stop rtl_eeprom doesn't crash, doesn't use threads, ends normally I'm not real practiced using gdb but I tried looking at a couple of core files, here's a run of rtl_fm: rtl_fm -f 162550000 -N - | play -t raw -r 24k -e signed-integer -b 16 -c 1 -V1 - -: (raw) Encoding: Signed PCM Channels: 1 @ 16-bit Samplerate: 24000Hz Replaygain: off Duration: unknown In:0.00% 00:00:00.00 [00:00:00.00] Out:0 [ | ] Clip:0 Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000013 Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Found Rafael Micro R820T tuner Oversampling input by: 42x.

I'm probably reading it wrong for all I know. I don't know what's causing the signal 6 either. I'd also like to get the -lrt of of the cmake files. OpenBSD doesn't use or have lrt, it works without. I can edit it out and compile, but every time I run cmake again, I have to edit the files again.
