Comment 4 Scott Gayou 2018-10-08 12:49:46 EDT

Upstream has two issues for what appears to be the exact same flaw.

See test1 run:

```
Audio File Library: file missing data -- read 0 frames, should be 5 [error 5]
==18400== Invalid write of size 4
==18400==    at 0x4E55C07: ??? (in /usr/lib64/libaudiofile.so.1.0.0)
==18400==    by 0x4E4C8E2: afReadFrames (in /usr/lib64/libaudiofile.so.1.0.0)
==18400==    by 0x401E4D: ??? (in /usr/bin/sfconvert)
==18400==    by 0x40162D: ??? (in /usr/bin/sfconvert)
==18400==    by 0x50913D4: (below main) (in /usr/lib64/libc-2.17.so)
```

and test2 run:
```
Audio File Library: file missing data -- read 0 frames, should be 5 [error 5]
==18402== Invalid write of size 4
==18402==    at 0x4E55C07: ??? (in /usr/lib64/libaudiofile.so.1.0.0)
