[fpc-pascal] Freeing memory with exceptions

[Benito van der Zander]

Hi,

I wrote all my code in Delphi 4. From 1998 or so. I do not make new 
projects, only maintain old ones.

Delphi 4 felt much better.

Like take:

procedure test;
var s: string;
begin
   s:= 'abc';
end;

And Delphi 4 produces great looking output. 64 bytes. A few mov and push 
for exception handling:


FPC nowadays. 103 bytes. 4 functions calls for exception handling! 3 
even if there are no exceptions. Unbelievable that it needs that many 
function calls

I wrote my own using pchars:
