Hi list, I’m really struggling to get my 32/64-bit VST plugin running in combination with JUCE. I already upgraded to the very last version of Juce (1.54.27). I only encounter problems in 64-bit hosts (eg. Plogue Bidule, Cubase 6). It seems to be a problem of shared allocation space between different 64-bit plugins. Because I couldn’t really find a solution to my problem, I downloaded the tutorial project from the VSTGUI4.0 library. It uses VSTSDK2.4 in combination with VSTGUI4.0. I included the juce\_amalgamated.mm file in the XCode project, and added the different frameworks Juce needs to compile. The only thing is that I added a Juce object to the plugin class (a StrinArray in this case). (and the include statement). Nothing else changed. This works in 32-bit, but not in 64-bit. It seems to have a problem with clearing memory. The crash logs are included below the code. When I remove the statement, the plugin work without crash. ```auto #ifndef __TutorialVST2Effect__ #define __TutorialVST2Effect__ #include "public.sdk/source/vst2.x/audioeffectx.h" #include "TutorialParameters.h" #include "juce.h" class TutorialVST2Effect : public AudioEffectX { public: TutorialVST2Effect (audioMasterCallback audioMaster); void processReplacing (float **inputs, float** outputs, VstInt32 sampleFrames); void setParameter (VstInt32 index, float value); float getParameter (VstInt32 index); protected: float parameters[kNumParameters]; StringArray presets; }; #endif // __TutorialVST2Effect__ ``` [quote]Process: Plogue Bidule [1833] Path: /Applications/Plogue Bidule 0.9716 (64-bit)/Plogue Bidule.app/Contents/MacOS/Plogue Bidule Identifier: com.plogue.bidule Version:

Could this have something to do with autorelease in cocoa? ---

Looks like a pretty straightforward dangling pointer type of mistake to me. Use your debugger! ---

When I put JUCE\_CHECK\_MEMORY\_LEAKS=0 the crash doesn’t occur anymore in this case (simple example plugin provided in the VST SDK). I don’t use a pointer… I just put StringArray presets as a class member. How can this lead to a dangling pointer? Still I have some very random crashes when using JUCE classes in other VST plugin. The debugger doesn’t really tell me a lot more. Is it because I’m accessing the JUCE objects from different threads (Audio and GUI)? Gilles ---

If you’ve been messing with that stringarray from two threads at once, then yeah, that might just possibly be the problem(!)
