[Coin-discuss] OsiPackedVector question

[Laszlo Ladanyi]

Hi Matt, 

You are entirely right. The destructor should be public. Only the constructor
needs to be protected to forbid the creation of objects whose real type is
OsiPackedVectorBase.

I'll commit the fix in a minute to both the main and the development
branches.
