[DUG] Is it a bug in latest version of Delphi? - Solution

[Rohit Gupta]

Jolyon,

As I mentioned I was reporting on things 7 years old, with failing 
memory quite common to my  age. 

And I am not going to spend the time searching for it to prove you right 
or wrong.  Again, from memory, Intel was changing the design of the 
memory manager which was going to mean that  a better definition of the 
null pointer would be  ffffffffff...  What happened with that, I do not 
know or care.

As for the rest, please pretend you are hearing the stereotypical Indian 
voice.

"Oh my golly gosh, thank you for clarifying that sir.  I must have spent 
months trying a billion solutions before I must have accidentally found 
the X2."

Did it not occur to you, that it works because I knew what I was 
doing....  :-)  And before you retort, I do not modify the vcl for any 
reason as it could lead to problems when using bpls on a clients machine 
where they already exist from some other application.
