The dmd compiler v2.046 produces correct output ("Error: module test from file
xxx.d conflicts with another module test from file yyy.d"), if multiple
placement of same module identifier are in the root of the project, however it
crashes, when the files are in a subfolder and does not display a proper error
message.

The output is:
Assertion failure: 'mprev' on line 641 in file 'module.c'

Test case:
--main.d--
import std.stdio;

import folder.File1;
import folder.File2;

int main(char[][] args)
{
    writefln(file2);
    return 0;
}

--folder\File1.d--
module folder;

const char[] file1 = "File1";

--folder\File2.d--
module folder;

const char[] file2 = "File2";
