Crash on exit (0xC000000D)

General JUCE discussion
1

Having troubles again with my audio plugin. When the host quits, the program crashes on windows with the code 0xC000000D (Invalid parameter to service or function). I didn't really realize when it happened, because it only happens in release mode, and i develop in debug mode. It might have been there since i started with juce for all i know.

In the release, x64 build, it throws the exception here (crt0dat.c: line 628 - function doexit()):

Heres the rest of the stacktrace not shown in the picture:

Originally, the x64 build failed with 0xC000005 but that was because it ignored the original exception, followed by a stack overflow exception, then the invalid exception. Breaking on all exceptions lead me there.

 

In the release, x32 build, it throws the exception here (juce_win32_DirectWriteTypeface.cpp: line 106)

~Direct2DFactories()
{
    d2dFactory = nullptr;  // (need to make sure these are released before deleting the DynamicLibrary objects)     
    directWriteFactory = nullptr; // <- crash
    systemFonts = nullptr;
}

Unfortunately, there's no meaningful stacktrace for x32 (just [external code] and this deconstructor). However, it seems to be clear that the exception happens on static storage destruction of some direct2d objects. I dont have any significant static data (besides some global boolean flags) that require destruction at exit to my knowledge.

Searching brought this up and it is exactly the same problem: http://www.juce.com/forum/topic/vst-plugin-crash-when-quit-host-latest-tip

However, JUCE_USE_DIRECTWRITE is already not defined in my project (#defining it didn't help either :))

e: I found it and disabling it does remove the crash. Not sure whether it's a loss not to have DirectWrite enabled? 

e2: same problem here: http://www.juce.com/forum/topic/showing-tooltip-directwrite-plugin-causes-host-crash

I'd appreciate any input..

The code that creates/destroys those objects is perfectly legit, but the destructor is being called as part of the runtime's static shutdown, so I'm guessing that there's an order-of-destruction problem - i.e. something else deep in the win32 libraries is being closed while the D2D stuff is still using it.

I've just refactored the code now so that instead of being a static object, the D2D stuff is created/destroyed according to its use. I don't know whether this will fix your exact issue, but I'd be interested to hear what happens..

Nice, I'll test it later.
