I have some questions:
1. why does it work with LDC?
2. why does it work with DMD when build/link in 2 step?
3. why it doesn't work when DMD is invoked once for build/link
I think these are probably coincidences and the answer can be
summarized as "that's what ends up happening due to the details
of the implementation".
4. is this a bug in DMD or my code is wrong?
I would say the code is wrong in principle, though as you've
noted it can still work in some specific circumstances.
5. if it's wrong, then why does it compile/no error?
`extern(C) main` is a low-level feature, because it effectively
turns off parts of the language. However, the rest of the program
doesn't know that this is the case - currently the compiler
simply assumes you know what you're doing. Maybe it's not OK that
it's easy to use it by accident.
