Segmentation fault
Opened this issue · 7 comments
On a Raspberry Pi, Raspbian jessie, using a USB microphone interface that does work with arecord.
When executing ./witd-arm -i plughw:1,0 -v 10:
[wit] initialized sox: 14.4.1
[wit] init state machine
[wit] initialized with device: plughw:1,0

Any idea?
Thanks for the report. Do text queries work? (http://localhost:9877/text?q=hello&access_token=***) And what about queries with end-of-speech detection disabled? (http://localhost:9877/start?access_token=*** and http://localhost:9877/stop)
stop and text works.
start without autoend outputs a lot of numbers:
[wit] error while sending: Some([0, 11, 0, 11, 0, 12, 0, 12, 0, 21, 0, 21, 0, 31, 0, 31, 0, 43, 0, 43, 0, 50, 0, 50, 0, 54, 0, 54, 0, 48, 0, 48, 0, 47, 0, 47, 0, 48, 0, 48, 0, 50, 0, 50, 0, 73, 0, 73, 0, 70, 0, 70, 0, 63, 0, 63, 0, 51, 0, 51, 0, 42, 0, 42, 0, 32, 0, 32, 0, 34, 0, 34, 0, 35, 0, 35, 0, 39, 0, 39, 0, 33, 0, 33, 0, 22, 0, 22, 0, 12, 0, 12, 0, 11, 0, 11, 0, 18, 0, 18])
We haven't had a chance to test witd-arm on Jessie yet. I updated witd-arm so that it contains debugging symbols. If you have time could you try running it inside gdb and showing a backtrace? (gdb --args ./witd-arm -i plughw:1,0 -v 10, then run, do the http request with autoend=true, and do bt when you get a segfault). This way we might be able to see what is failing.

Hi Emile, we are looking into the issue.
Awesome, thanks. If i can help, let me know!
I'll try to reproduce your issue today and let you know what I get. Thank you for your patience!
