Within my compiler, each single number takes a 64-byte record to
represent. So 1MB of data takes 64MB, while a 1MB string takes one
64-byte record plus the 1MB of the string data.
 
Then there are the various type analysis and other passes that have
to be done a million times rather then once. I'd imagine that
compilers like gcc do a lot more.
 

For gcc up to certain limit I measured ~160 bytes per number.
After that certain very big limit (probably 64M numbers) gcc appears
to switch into more economical mode - ~112 bytes per number. At ~300M
numbers it appears to become yet more economical, but still above 100
bytes per number. 400M number - 100  bytes per number. Going further
became quite time consuming so I gave up.
