Subject: [fpc-pascal] Debugging ancient
heap allocation
seems not to have received a reply. The problem of debugging
memory allocation, however, is wider and not just involving
ancient code!
I am using:
Compiler 2.4

This program:
Program TestMem ;
Const ASize = 1000 ;
Type DataA = Array Of Longint ;
Var A : DataA ;
Procedure Init(Out X : DataA ; Const N : Longint) ;
Begin
Writeln(Length(X)) ; { Writes: 0 }
End ;
Begin
SetLength(A, ASize) ;
Writeln(Length(A)) ; { Writes: 1000 as expected }
Init(A, ASiz

As part of an attempt at multi-threading, I have had to move
many things that used to be global into the Implementation
parts of units in order to enforce privacy. When I moved a
routine passed as a parameter and put it inside the routine
to be threaded, the program ceased to work. I append the

A really smart compiler would notice that this in this loop the value of
vd is never examined, the loop being equivalent to

After using BlockRead to fill a 2D dynamic array, I get an access violation on
the
very first reference. A 2D array with only one dimension dynamic works OK.
What am I missing?
Windows, FPC 2.2.2, 2.2.4 or 2.4.2.
Program WriteA ; { Write a binary file using using static array and BlockWrite }
