--- Comment #15 from Bernhard Übelacker  ---
Created attachment 75535

test.cpp for testing high-entropy-va, with some results inside.

Could be the key another "OPTIONAL HEADER VALUE" / DllCharacteristics?

I found a test program with "High Entropy Virtual Addresses" enabled seems to
behave different on windows than one with it disabled.
(cl option /HIGHENTROPYVA)

Mingw side shows this as "HIGH_ENTROPY_VA".
(gcc option -Wl,--high-entropy-va)

Attached test program shows a few example outputs.
And at least the executables from #55809 and #55761
do not show "HIGH_ENTROPY_VA", therefore they seem
to get the low addresses in windows.
