>          Issue Type: Bug
>      Security Level: None
>          Components: Formats/General
>    Affects Versions: 13.30.0

> I've built a voice recognition system for german digits using asterisk 13, pocketsphinx and a plugin and server (based on astsphinx) to connect asterisk with pocketsphinx. When testing the system with calls where wav files are played to the recognition engine everything works fine until about the 50th call. Asterisk then crashes with a segmentation fault and restarts. Reading the gdb backtrace I've found out that the problem occurs, when the format codec id is selected.
