Doesn't really help.
a := 'abcdefghi' does allocate 9 bytes of RAM. I can access a and b
after it is assigned. The problem is StrCopy crashes. I would expect
"a" to have the same string as b once this is executed.

var
a: pChar;
b: pChar;
begin
a := 'abcdefghi';
b := 'jklmnopqr';
StrCopy(a,b);
end;
Question: Why does this code crash?
