[fpc-pascal]Memory leak in freepascal, FreeAndNil not working properly?

What kind of answer is this? That it is not working in Kylix either does 
certainly not mean their memory handling is correct. 

Please look at the code. The crash is supposed to happen, because it is the 
same object, that is addressed both times I say FreeAndNil. 
But that means, that FreeAndNil is not working properly and due to that 
TList.pack can't work because it is not a nil-pointer, that's coming back 
from FreeAndNil.
Otherwise it can't be possible, to address the same object again after calling 
FreeAndNil.
