Comment (by RJVB):

 Seems they reverted the fix again...

 I'm attaching a patch (to be applied to the portdir) which renames the
 patch that touched VSTEffect.cpp and improves it. The code is now 64-bit
 safer and handles initialisation of the mResource member in a way that
 should be compatible with libstdc++ . This is apparently where the error
 was.

 The modified code compiles with clang++5/libc++ on Mac, and doesn't get
 flagged when parsing against libstdc++ on Linux (as far as I can check
 this, of course). I don't have VST plugins so I have not been able to test
 runtime behaviour.
