Segmentation fault when switching modes about shinysdr

[kpreid]

I know of one cause of a segmentation fault, this GNU Radio bug. To check if it's the same thing, please take a look at the crash dump dialog (if you don't get one, try defaults write com.apple.CrashReporter DialogType developer, and same but with basic instead of developer to revert back) and see if it contains the same trace in the "Crashed" thread (or attach the text of the dump here for me to look at).

The Map should work, it's just that there's no UI whatsoever for putting things on it, nor even an intentionally-blank background. Confusing, I agree.

Here is the dump: http://pastebin.com/Qjy1esqJ

Yes, that's GNU Radio bug #614. It'll be fixed in GR 3.7.3.

A workaround is to change your ~/.volk/volk_config so that the line for volk_32f_s32f_multiply_32f does not specify a_sse, but something unaligned such as u_orc (or, I suppose, u_sse). If you don't have a volk_config file, then first try running the volk_profile command to create it; if it selects something unaligned by profiling then you're good. Running volk_profile should also reduce CPU usage of ShinySDR and other GNU Radio applications.
