Description GstBlub 2017-08-14 20:57:06 UTC 
We're seeing a crash on ARM NEON platforms when resampling pcm audio from 192k/24 down to 44.1k/16 with resample-method=cubic and quality=0

Program received signal SIGSEGV, Segmentation fault.

Comment 1 GstBlub 2017-08-14 21:01:18 UTC 
Resampling from 96k/24 to 44.1k/16 works, though.
Comment 2 GstBlub 2017-08-16 14:53:27 UTC 
This reproduces the crash, using this .wav file: http://www.kozco.com/tech/piano2.wav

gst-launch-1.0 -v filesrc location=/tmp/piano2.wav ! wavparse ! audioconvert ! audioresample quality=0 resample-method=cubic ! "audio/x-raw,format=S24LE,channels=2,layout=interleaved,rate=192000" ! audioco
nvert ! audioresample quality=0 resample-method=cubic ! "audio/x-raw,format=S16LE,channels=2,layout=interleaved,rate=44100" ! fakesink
Comment 3 GstBlub 2017-08-16 16:06:54 UTC 
Downsampling from 48k/24 town to 44.1/16 with resample-method=linear also crashes:

gst-launch-1.0 -v filesrc location=/tmp/piano2.wav ! wavparse ! audioconvert ! audioresample quality=0 resample-method=cubic ! "audio/x-raw,format=S24LE,channels=2,layout=interleaved,rate=48000" ! audiocon
vert ! audioresample quality=0 resample-method=linear ! "audio/x-raw,format=S16LE,channels=2,layout=interleaved,rate=44100" ! fakesink
Comment 4 GstBlub 2017-09-29 15:26:41 UTC 
FYI, this was working fine in 1.6.3.
