LDC 1.7.0 builds just fine.

There are similar error messages when compiling on linux, but 
they don't error out (linking succeeds despite them).

I don't have a reduced testcase yet. I figured I'd ask if it's 
something known before making the effort.

Are you by any chance mixing debug and release builds? Or are the 
-version specifiers different when compiling the various parts of your 
program? Check your compiler flags and ansure that they are the same 
over your entire build process. Especiall -debug -relase -inline -O -version

Admittedly I am alternating between building debug and unittest 
builds, but I'm only using dub, no separate compilation. I have 
limited control of the version specifiers other than through the 
build configurations, so there's not a whole lot to mix.

None of the (version specifiers in the) build configurations I 
have touch upon the part of the fairly innocent code mentioned in 
the error message, if I'm reading it right.

struct Foo
{
     this(Regex!char) { /* ... */ }
     this(StaticRegex!char) { /* ... */ }
}

It seems like the problem there is that StaticRegex is only an 
alias to Regex, so I'm overloading it twice. It rhymes well with 
the linked bug.

/++
     A $(D StaticRegex) is $(D Regex) object that contains D code 
specially
     generated at compile-time to speed up matching.
     No longer used, kept as alias to Regex for backwards 
compatibility.
+/
public alias StaticRegex = Regex;  // <--

Reducing it to just that doesn't reproduce the error message 
though. As long as Regex!char can house both ctRegex!"foo" and 
"foo".regex it works for me.

I think your case is this bug:
