dynamic_cast error with FrameLib in Max

[Former user]

I am making a new object for FrameLib, and while testing through xcode I get this dynamic cast error.

2019-03-31 15:18:24.634319+0100 Max[27021:387769] dynamic_cast error 2: One or more of the following type_info's has hidden visibility. They should all have public visibility. 15FrameLib_ObjectI14FrameLib_BlockE, 15FrameLib_ToHost, 12FrameLib_DSP.

No matter what object's I put into my patch they will produce this error and extent the list of objects that 'should have public visibility'.

This is beyond me c++ wise, but could it be an issue just with me - or have I caught something that might not have been detected at a previous commit?

I know about the error, but it appears to be harmless, as the cast still works.

I fixed it
