Why would you want this, or better why should two cStrings point to the same 
buffer? 

From what I can see, cBuffer was intended to be constructed with TakePointer = 
false, in that case the string is duped anyway, or with true in which case 
you handed over the buffer to cString and shouldn't use it further.

Anyway, if those two strings that point to the same buffer are destroyed, the 
buffer becomes free'd twice, which is certainly illegal as well :-)
