In commit e40a8b1e2c8b0962c7f99fed998db97e0a63472a I get crash when I click "unload samples" and got this messages

I think this issues doesn't happen only in debug mode, probably it is not the best fix, but the problem seems to be fixed if this asssert line in OgraMath.h, commented, I got no more crashes, how I think it is not the best fix, I only send you a diff to you figure out what I mean.
