In previous quoted sentence you refer  not to use development code. The
problem with issue 4922 force using development code and that is all -
cascade bugs are expected using unstable releases. I suppose you are not
willing to point to code for solution 4922 in order to correct sources in
2.0.2 and use it.

As GNU linker is very problematic on Win32, it was reasonable step to test
internal linker when development code is using.

I comparing code produced with the same compiler parameters, except -Xi .
Perhaps -Xi in that release disabled or enabled some other parameter(s). Or
command "make clean all" did not clean all previous produced code. That is
not possible to be determinated at the moment

The fact is that after manual cleaning directory and using the latest SVN
release internal llinked worked, produced Lazarus executable using internal
linker (without using -Xi and deleted LD.exe) was 39MB. Stripping gaves 33MB
and  executing fails. It seems that strip utility removed critical executing
code from header.

Duration compiling complete Lazarus code is about 6 times worst than with
LD. Regarding reported problem using not only phisical memory, creating map
file spend most of the time. Since this is development release, after
correcting problem with using memory, disabling creating map file and
checking problem with mentioned problem with (possibly incorrect) executable
heeader, linker will probably be near to Delphi's.

Good lack.
