I get an error "The application failed to initialize properly (0x0e0440001)" when trying to run an executable built with -cov. It happens both for release and debug builds (the same exe/dll runs without cov).

Could the problem be that I'm using -cov on my dll...?

I'm using dmd 1.022

That error code is DMD's SEH error code.  I think an exception is being thrown and not caught.

Is your DLL linked so that it will be loaded when your program runs?  Or do you manually load it with Win API calls?  It sounds like the former, so I'd have a look and see if your DLL is throwing an exception perhaps in the DLLMain.

Oh, one last question, I guess: I'm assuming your DLL is also written in D, is this so?

Strange... It doesn't throw an exception in release or debug without -cov.

Yep, the former. At least I'm not raising any exceptions there. DllMain is the simplest version (the sample from digitalmars)

Yes

It might be that the DLL is expecting something from the executable this isn't there (I known more about -cov then DLL's so take that with a grain of salt).

Are you using -cov on the .exe?

Because of -cov then? As it works in release and debug otherwise.

Yes, both compiled with -cov

Ok, I'm stumped.

There might be a function you need to call in DLLmain to initialize the code coverage (in much the same way as you need to manually run the unit tests).
The DMD docs about DLL's are from before the -cov option existed.
