Hello,
I've take a look at you RTL compile script and found the mess with the compiler
options.
When compiling RTL you should disable reading of options from fpc.cfg using the
-n switch.
When compiling the system unit use the -Us switch.
Additionally specify only CPU/Target and optimization options -O<x>.
No other options are required for Windows RTL.
When RTL is properly compiled, even with -O2, your test program works without
memory leaks.

RTL not modified. Just recompilation of 'sysinitpas.pp' unit with some
options causes problem.
Here is another test project that uses your current official FPC
installation with unmodified RTL:
http://dl.free.fr/ePtkQwgJJ
Test project contains source of 'sysinitpas.pp' (and required
'sysinit.inc', 'systlsdir.inc').
Used version 3.2.2 RC1. If you have another - get sources for your version.
Script 'compile.bat' compiles 'sysinitpas.pp' and then - test project
'test.pp'.
See comments inside.
'test_bad.exe' shows growing memory consumption.
Hello,
Your test program runs fine when compiled with FPC 3.2.0 using the
official RTL compiled with -O2. No memory leak.
I suppose the issue is caused by your modifications to RTL. -O2
(regvars) just triggers the problem in the modified RTL code which is
hidden when regvars are disabled.
