There's a related issue regarding CRT ctors - if both executable and library
contain an identically mangled `pragma(crt_constructor)` function (doesn't even
need to be in the same module - and name collision is quite likely due to the
`extern(C)` requirement...), the executable one is invoked twice. Again
DMD-specific, works with LDC.

Further tests have shown that with DMD, the ModuleInfos of modules contained in
both executable and library are apparently resolved to the executable's.

E.g., versioning out the module ctor in `modcon2.d` for the library still leads
to it being invoked when loading the library; the opposite case, versioning it
out for the executable, means it's not invoked at all.

This 'works' with LDC v1.27 (but DMD v2.097 still fails):

I think this is more likely related to compiler differences wrt. relocation
model, not a druntime divergence.
