people who do not really understand why 32 bit systems are a
really problematic even if the apps don't use more than 2 GiB
of memory.
Here's Linus Torvalds classic rant about 64 bit
https://cl4ssic4l.wordpress.com/2011/05/24/linus-torvalds-about-pae/ (it's
more about PAE but the reasons why 64 bits is a good thing in general are the
same: address space!)
Why can't you use both 32bit and 64bit pointers when compiling
for x86_64?
My guess would be that using 64bit registers precludes the use
of 32bit registers.
You can, but OSes usually give you randomized memory layout as a
security measure.
