That is the memory that had been used before the memory manager of the heaptrc unit had been setup. Remember that there's first the System unit initialization and only then the initialization of the heaptrc unit.

[fpc-pascal] Access violation in an empty project declaring heaptrc
Hello, Just create a project like this: program project1; {$mode objfpc}{$H+} uses heaptrc; begin end. Now, compile and try to run that, you will get this error: Heap dump by heaptrc unit 0 memory blocks allocated : 0/0 0 memory blocks freed : 0/0 0 unfreed memory blocks : 0 True heap size : 131072 (1856 used in System startup) True free heap : 129216 An unhandled exception occurred at $770E8E19: EAccessViolation: Access violation $770E8E19 $770E8D28 $0040A8C9 $0040A456 $00413BC2 Why an access violation in an empty project, is it a heaptrc bug? Now, if you compile and run this project below with -gh: program project1; {$mode objfpc}{$H+} begin end. You will get: Heap dump by heaptrc unit 47 memory blocks allocated : 1173/1280 47 memory blocks freed : 1173/1280 0 unfreed memory blocks : 0 True heap size : 163840 (112 used in System startup) True free heap : 163728 What means "112 used in System startup"? I have a project that in some cases I get: Heap dump by heaptrc unit 90 memory blocks allocated : 2827/3072 90 memory blocks freed : 2827/3072 0 unfreed memory blocks : 0 True heap size : 196608 True free heap : 196480 Should be : 196608 So it seems that the "Should be : 196608" in this case is related to the 128 used in the system startup, because when I comment all the code in this project I get "128 used in System startup". -- Silvio Clécio ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
