Summary: Crash in ast_readaudio_callback
Description:
We're experiencing almost-daily crashes in ast_readaudio_callback.
There seems to be corruption in the ast_filestream structure.
At first we thought it was just another appearance of issue 15616 (random
crashes) but currently we're experiencing the same crash at the same
point.
Every time it's a different agent, and a different extension. We have been
completely unable to reproduce this behaviour. It occurs at seemingly
random moments.
