After debugging it in more detail i found the code but doesn't know what is wrong here:

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES);
    NSString *applicationSupportDirectory = [paths objectAtIndex:0];

    const std::string returnString([applicationSupportDirectory UTF8String]);

    // Cleanup the NSArray and the NSString
    [paths release];
    [applicationSupportDirectory release];

    return returnString;

After I changed it to the following everthing is working fine:

    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES);
    NSString *applicationSupportDirectory = [paths objectAtIndex:0];

    const std::string returnString([applicationSupportDirectory UTF8String]);

    // Cleanup the NSArray and the NSString
    [pool release];
    return returnString;

So, is the manual release wrong and is the memory being freed in the second example?

Best Regards

[applicationSupportDirectory release] is definitely wrong as it is just pointing to an item in the paths array. Doing a quick Google search for NSSearchPathForDirectoriesInDomains it seems you don't need to free up paths either (although some people claim it leaks memory).

So I don't think you need to release either, though I am not an objective C expert. If this is the case then using the NSAutoReleasePool will have no effect.

Seems to be crashing in an NSAutoreleasePool release, but it is crashing in the Illustrator app rather than your plugin. Do you use NSAutoreleasePool in your code? Maybe it is crashing when Illustrator tries to load your plugin. Do you have anything strange in your Info.plist or your plugin's rsrc file? Do you see any errors in the console window?
