Hello,

Just upgraded to latest Juce version, recompiled AudioPluginHost (enabled vst2) - I get asserts when JUCE\_VST\_WRAPPER\_INVOKE\_MAIN is called; if I continue past the assert everything seems to run just fine. But why the assert? And exactly what gets asserted? I see no jasserts anywhere there - JUCE\_VST\_WRAPPER\_INVOKE\_MAIN expands to

```auto
#ifndef JUCE_VST_WRAPPER_INVOKE_MAIN
#define JUCE_VST_WRAPPER_INVOKE_MAIN effect = module->moduleMain ((Vst2::audioMasterCallback) &audioMaster);
#endif

```

Anyone any idea what’s up here?

Cheers,

Tom

Bump. I can’t believe I am the only one seeing this?
