EXCEPTION_ACCESS_VIOLATION_READ

[HDalsfelt]

Hi (again)

We have a pretty rare EXCEPTION_ACCESS_VIOLATION_READ-crash with the following call stack:

(Since I don't have the symbols it's a bit hard to read)

ProjectAcousticsWwise ProjectAcousticsWwise ProjectAcousticsWwise ProjectAcousticsWwise ProjectAcousticsWwise ProjectAcousticsWwise ProjectAcousticsWwise ProjectAcousticsWwise Alara!CAkBusFX::Processor::Execute() [D:\Jenkins\ws\wwise_v2021.1\Wwise\SDK\source\SoundEngine\AkAudiolib\SoftwarePipeline\AkVPLMixBusNode.cpp:2669] Alara!CAkVPLMixBusNode::ProcessInputAndPushToConnections() [D:\Jenkins\ws\wwise_v2021.1\Wwise\SDK\source\SoundEngine\AkAudiolib\SoftwarePipeline\AkVPLMixBusNode.cpp:2133] Alara!CAkLEngine::SoftwarePerform() [D:\Jenkins\ws\wwise_v2021.1\Wwise\SDK\source\SoundEngine\AkAudiolib\SoftwarePipeline\AkLEngine_SoftwarePipeline.cpp:2898] Alara!CAkLEngine::Perform() [D:\Jenkins\ws\wwise_v2021.1\Wwise\SDK\source\SoundEngine\AkAudiolib\Win32\AkLEngine.cpp:693] Alara!CAkAudioMgr::Perform() [D:\Jenkins\ws\wwise_v2021.1\Wwise\SDK\source\SoundEngine\AkAudiolib\Common\AkAudioMgr.cpp:611] Alara!CAkAudioThread::EventMgrThreadFunc() [D:\Jenkins\ws\wwise_v2021.1\Wwise\SDK\source\SoundEngine\AkAudiolib\Win32\AkAudioThread.cpp:75] kernel32 ntdll

I understand it's hard to tell from this input, but do you have any idea what might cause something like this? It might eventually have something to do with switching view targets (switching listener positions) but I haven't been able to create a repro.

Best,
