The test case, reduced as much as I easily could achieve (I spent too much time
on this already, maybe I've missed something obvious):

a.d:
---
import c;
---

b.d:
---
import c;

int regex(string pattern)
{
  return 0;
}

bool match(string r)
{
  return true;
}

void applyNoRemoveRegex()
{
  void scan(string[] noRemoveStr, string e)
  {
    auto a = find!((a){return match(e);})(map!regex(noRemoveStr));
  }
}
---

c.d:
---
template map(alias fun) {
  auto map(Range)(Range r) {
    struct Result
    {
       property auto ref front()
      {
        return fun("a");
      }
    }
    return Result();
  }
}

Range find(alias pred, Range)(Range haystack) {
  pred(haystack.front);
  return haystack;
}
---

$ dmd -c a.d b.d
Assertion failed: (!vthis->csym), function toObjFile, file glue.c, line 719.
Abort trap: 6

If you reverse the source files in the dmd parameter list, the example compiles
fine.

The bug was found by trying to compile DustMite with DMD 2.054
(https://github.com/CyberShadow/DustMite/wiki/Building-DustMite).

Probably related, yes, but I don't know if it is really the same bug, as it
depends on multiple modules, etc.

Looks like bug 2962 to me.

Same result but with different test case in issue 8348.
