Cool, passing --DRT-covopt="merge:1" did the trick.

Thanks!

Speaking of which, are the --DRT-* options documented anywhere?? I don't even know where to begin to look, besides in the druntime code itself.

I think you're looking for: "Controlling the Coverage Analyser" under https://dlang.org/articles/code_coverage.html.

Ah, thanks!  That's exactly what I was looking for.

Still, it would be nice to have a list of all --DRT-* options (not necessarily related to coverage) somewhere, just for reference.
