Three legitimate bugs? (D1.061)

The general answer to this question is: Yes, as long as
* you're sure it's a bug
* you can reproduce it in a current version of DMD or GDC
* it isn't already reported

The bug reporting system is here:

Puzzling.  It appears that line 2 is somehow helping the compiler to get 
it right - and without it, the compiler gets thrown while trying to make 
sense of the S() you're setting S2 to.  But the line numbers you're 
getting are puzzling in any case.

In any case, there's certainly a bug here.

That's certainly a bug that needs to be reported if it isn't reported 
already.

The error should be "undefined identifier random".

Indeed, this is probably a bug along the same lines as the compiler's 
tendency to treat invalid expressions as being subsequently of type int.
