From: Alex Smith <alex.sm...@warpsharp.info> The appropriate flag for HEASLR (--high-entropy-va) was added in binutils 2.25.
Also set the image base >4GB so higher entropy gets applied to image base randomization when used with HEASLR (8 -> 17 bits of randomization). Windows does this for compatibility because of "latent pointer truncation issues".
