[Audacity-devel] Crash with Sound Activated Recording

[Michael S. <msc...@gm...>]

Audacity 1.3.9-beta

There's a race-condition in AudioIO::StartStream() and
AudioIO::SetMeters(), which affects audacityAudioCallback() and leads to a
crash when enabling "Sound Activated Recording".

At the start of a recording, the callback may run into mInputMeter still
being NULL, which causes it to crash when trying to call the input meter's
GetMaxPeak() method.
