Description
To reproduce, use AudioRecorder app.
1. Select audio codec A-EC3 (has a buffer size of 12288 bytes
2. Record audio and stop
3. Select audio codec AAC (has a buffer size of 8192)
4. Record audio and stop
5. If app did not crash, repeat from 1
The reason is a bug in the logic for sending audio buffers. An internal 'm_pcm' array is used to accumulate data, but if this array size is greater than the current buffer size, the application crashes when copying a negative number of bytes.
