Alrighty, we've found at least one issue that was definitely a potential 
culprit on 32-bit (all os) and only since the 64-bit release.  basically, 
float and complex local variables where not being properly popped from the 
operand stack correctly.

I uploaded a build ( for you as well as for Michael and 
anyone else who may want to test particular issues:


It includes a win32 build and an osx64 build, as well as source for all 
supported platforms.

If you'd like, please give it a spin!
