[New-bugs-announce] [issue35253] Linker warning LNK4281

New submission from Jorge Ramos <neyuru at gmail.com>:

When building python 3.6.7 x64 from source I get multiple warnings:

LINK : LNK4281 - "undesirable base address 0x1D110000 for x64 image; set base address above 4GB for best ASLR optimization".

after that, the build gives the offending module: 


(e.g., there are many others) the .. means whatever parent directory the build files are on. I use the following batch file:

Tools\msi\buildrelease.bat -x64 --pgo '-m test -q --pgo'

Is this a problem?
