#300 sox v14.4.2 segmentation violation when playing some wav files generated by Audacity
sox v14.4.2 segmentation violation when playing some wav files generated by Audacity:
the command sox testfile.wav --default-device
plays the contents of testfile.wav, then plays some "scrambled" contents that sound like a tape recorder on fast-forward, then core dumps with a segmentation violation. The problematic files all play fine in Audacity and VLC player. The problematic files were recorded and exported from Audacity. This happens to some but not all wav files. Soxi shows no commonality or corruption in file headers of rprobematic files. Two example problematic files have been attached.
This segmentation violation happens with the sox.exe v14.4.2 obtained from cygwin32 distribution, as well as with sox compiled from github sources.

added attachment "beginvox.wav" because that's the input filename that the -V listing refers to.
Problem confirmed on Linux as well.
