Michael,
I believe there is a memleak but I couldn't found.
I've just created a route that calls Application.Terminate and I got this:
===BEGIN===
Heap dump by heaptrc unit
387 memory blocks allocated : 18658/19944
385 memory blocks freed : 18626/19912
2 unfreed memory blocks : 32
True heap size : 196608 (96 used in System startup)
True free heap : 196320
Should be : 196352
Call trace for block $034CA470 size 16

$00437268

Here is my test program:
===BEGIN===
program demo;
{$define STANDALONE}
uses
SysUtils,
httpdefs, httproute,
{$ifdef STANDALONE}
fphttpapp,
{$endif}
{$ifdef FCGI}
fpfcgi,
{$endif}
IniFiles;
{$ifdef STANDALONE}
procedure TerminateCallBack({%H-}ARequest: TRequest; {%H-}AResponse: TResponse);
begin
Application.Terminate;
end;
procedure ConfigureStandalone;
begin
heaptrc.SetHeapTraceOutput('log.txt');
heaptrc.GlobalSkipIfNoLeaks := True;
heaptrc.HaltOnError := False;
with TIniFile.Create('demo.ini') do
try
Application.Port := ReadInteger('Standalone','Port',8080);
finally
Free;
end;
HTTPRouter.RegisterRoute('quit', rmAll, @TerminateCallBack, True);
end;
{$endif}
begin
{$ifdef STANDALONE}
ConfigureStandalone;
{$endif}
Application.Initialize;
Application.Run;
end.
===END===
My environment is: Lazarus 1.8.3 r57764 FPC 3.0.4 i386-win32-win32/win64
