I'm running into this linker error
   Error 42: Symbol Undefined _D18TypeInfo_AC6Object6__initZ
with the recent DMD versions (1.004 right now), and I don't really know what's going on. I don't get this error with older DMD`s.

Anyone have any ideas?

The strange part is the error goes away when using -release

I guess the Z on the end means it's related to template?

No, it doesn't have anything to do with templates.

It's the TypeInfo instance for Object[], aka typeid(Object[]). It /should/ be generated when needed...

Do you have some (preferably short) example code that shows this error?

I get this when trying to compile a DWT app with dmd 1.004.  Works fine with dmd 1.0 and older.  It also happened with one of the dwt examples, think it was test_rowlayout.d.

Looks similar to what Chris got, since it's a missing TypeInfo object.
