Hi Matti, after double checking pypy-c.exe headers with
dumpbin /headers pypy-c.exe (actually while objects are compiled with /LARGEADDRESSAWARE flag in windows.py - final exe does not contain required flag so possibly here - either this flag should be removed or set correctly such that produced exe has needed headers as might be expected from setting /LARGEADDRESSAWARE flag in code - will look into this in my merge request) and running editbin /LARGEADDRESSAWARE pypy-c.exe I achieved compilation of pypy by pypy but I also set BCDEDIT /Set IncreaseUserVa 3072 so my intent before pull request is a) to check that /LARGEADDRESSAWARE flag in windows.py start to work b) will check several times to be sure if BCDEDIT /Set IncreaseUserVa 3072 is really needed to work. when I'm done will submit code and if it actually needed - also docs to compile pypy on windows 64 could be changed such that it it does not require additional efforts to investigate.
