What steps will reproduce the problem?
1.Create a new empty Intraweb project using default options
2.Include ScaleMM2 as the first unit in your .DPR file
3.Build and run the application
There will be an Assert error:
Debugger Exception Notification
Project Project1.exe raised exception class EAssertionFailed with message
'Assertion failure (...\smmGlobal.pas, line 264)'.
Extracted from smmGlobal.pas:
procedure TGlobalMemManager.FreeMediumBlockMemory(
aBlockMem: PMediumBlockMemory);
var
firstmem: PMediumHeader;
begin
//keep max 10 blocks in buffer
//if FFreeBlockCount >= 10 then
begin
firstmem := PMediumHeader( NativeUInt(aBlockMem) + SizeOf(TMediumBlockMemory));
//is free mem?
//if NativeUInt(firstmem.NextMem) > NativeUInt(1 shl 31) then
if firstmem.Size and 1 <> 0 then
begin
//fully free mem? we can only release fully free mem (duh...)
if PMediumHeaderExt(firstmem).ArrayPosition = 16 then
begin
//RELEASE TO WINDOWS
VirtualFree(aBlockMem, 0 {all}, MEM_RELEASE);
//exit!
Exit;
end;
end;
Assert(False); <--- ERROR HERE
end;
Using latest version from ScaleMM2 + BDS2006 + IW10 under WindowsXP SP3

ScaleMM2 has some flaws, which cannot be fixed (easily)
try ScaleMM3 instead:

(note: use "raw file" to download code in webbrowser)

Because of my investigation of available MM's (see result:
http://delphitools.info/2011/10/13/memory-manager-investigations/)
I gave it another try.
Thanks to your test with Intraweb I was able to find some problems!
(just because it did some other memory calls, so problems where early visible,
which is easier to debug/test).
I will do some cleanup and post the results soon

Hi!
I'm glad that I could help with a small thing! :-)
Looking forward to see your new MM in action!
