This happens often. People that have more experience in D use it in the way it 
is meant to be used, so they follow the normal usage patterns, that are often 
tested enough (or have already known bugs).
But newbies sometimes use D features in ways they where not meant to be used, 
so they go out of the well walked down footpath (I don't know how this is 
written in English), so they can often find bugs.

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.


Ouch! I hate it when newbies hit compiler crashes.
I've created a bug report:
http://d.puremagic.com/issues/show_bug.cgi?id=4242

Hope to create a patch for it in the next few days.

Bug: compiler crash when using module name twice

[Matthias]

I'm very new to D and misused the module identifier, I thought it would 
be the namespace/package name.


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";

Used Code::Blocks.
