[fpc-pascal] dynamic array and new/dispose

I am compiling in a delphi mode.
Sorry for not posting a runnable source code,. 
The code portion was taken from a huge source code, which is probably hard
to detach from the rest of the code.
It is reading a TStream object, which is an input 3ds file given to the app.

Are you compiling in Delphi mode? Please *always* post compilable  
source code that demonstrates the problem when asking for help, not  
uncompilable snippets. Don't make people guess about what you might  
have written or about how you are compiling it.
