This code gives distinct results when compiled for Win32 and Win64
- Win32: 49744125
- Win64: 49744124.999
procedure Test;
var
D: Double;
begin
D := 3 * (exp(3 * ln(255)));
WriteLn('Result: ' + FloatToStr(D));
end;
Somewhere is precision loss (or extra rounding). Is this good?

Sorry, earlier I try your hint - and result was bad.
Perhaps I did something wrong.
But I repeat it now - and it is working. Thank you again.
Finally my working build script look like this:
set UNITS_PATH=.\packages\*
set
Unfortunately I tried it and this doesn't work.
Problem only with 'sysinitpas.pp' unit.
He is not depends on other RTL units, but linked into final executable by
compiler.
I suppose, compiler itself depends on internal layout of this unit.
And a solution is to compile 'sysinitpas.pp' with the same
Thank you, i will try this.

Here is another test project that uses your current official FPC
installation with unmodified RTL:

Test project contains source of 'sysinitpas.pp' (and required
ompiler and minimal RTL):

Answer for my previous message
(https://lists.freepascal.org/pipermail/fpc-devel/2021-January/043512.html).
Memory leak happens when unit 'rtl\win32\sysinitpas.pp' compiled with
"-O2" or higher.
To eliminate this bug add "-O-" or "-OoNOREGVAR" to command-line when
compile this unit. This disables
I am using custom build of minimal FPC RTL and found possible bug. When
unit 'system' (or some other?) compiled using -O2 (or higher) option in
'fpc.cfg', then application, compiled using this unit, increase memory
usage every time BeginThread() function is called.
This appears on FPC 3.2.0 and

Not special for this RC but some bugs:

1) packages\winunits-base\src\wininet.pp
Compilation error in -Mdelphiunicode: bad
