A 32-bit executable is limited to 4 GB of RAM on a 64-bit kernel. If you're 
running a 32-bit kernel, then the limit drops to 3 GB.

At the very least, make sure you're using gold, not ld.bfd. But my 
recommendation stands, especially for developers.

I'm also not asking for a cross-compilation. I'm asking for a native linker 
that is a 64-bit executable that your 64-bit CPU and 64-bit kernel can execute 
natively anyway.
