Really? When you run map2.rb you see "hello"?
When I run map2.rb I get the same address. But when I run map2.rb I get an
error at mmap.rb, line 270: 'load - marshal data too short'. It seems that I'm
getting an empty buffer from the memcpy, but I don't understand why.
I just tried this at work, too - same result.
