Multires crash on Mac

Hello

I’m currently learning multires modeling in Blender, and have been working on a model on my PC. I’ve been able to go up and down multires Levels with no problem on my PC (with the exception of normal slowness at higher levels). When I move the file to my Mac laptop, the program crashes the second I attempt to raise or lower the levels. Is this a compatibility problem? Should I stay with one platform at all times?

Thanks

Go to http://www.blender.org/development/report-a-bug/ and reporting it as a bug, if no one has already. If someone has there’s probably a solution.
