Loop through it and allocate each one rather than trying to do it 
in a one liner like that.

The debug info sometimes shows the previous line instead of the 
current line. I betcha if you put some other random thing in 
between like a writeln() it would show that new thing as the line 
number it failed on. I think it is the address of the crash shows 
the last instruction actually finished but I'm not sure.
