If you're linking against the custom druntime with Objective-C support (as it happens normally with this test), the culprit may well be in one of those druntime objc support functions too. In this case _dobjc_throwAs_d is referenced (which will convert Objective-C exceptions to D exceptions).

It'll probably fail too, but in this case if you comment out the function calls made through the selector variables (so it won't reference anything special in druntime for exceptions) and you'll have a much more isolated test.

The reason why I'm suspecting the selectors is, I run an object dumper that I found in the linker sources. It fails on line 402:

http://www.opensource.apple.com/source/ld64/ld64-134.9/ld64-134.9/src/other/ObjectDump.cpp

I printed "leftString" and "rightString", and run the tool on an object file that works, they both contain selector names.
