digitalmars.D - Bug when initializing multiple variables by static opCall (dmd v0.113)

Hi!

I am new to D and every now and then I get some errors that seem like 
bugs. I didn't find any bug report system so am I expected to report here?

struct Pose
{
   vec3 mTranslate;
   quat mRotate;
   vec3 mScale;
   static Pose opCall()
   {
     Pose p;
     p.mTranslate = vec3(0,0,0);
     p.mRotate.identity();
     p.mScale = vec3(1,1,1);
     return p;
   }
}

void test()
{
   Pose mDefaultPose;
   Pose mCurrentPose;

   mCurrentPose = mDefaultPose = Pose(); // ERROR

   mCurrentPose = Pose(); // NO
   mDefaultPose = Pose(); // ERROR
}

dmd -Isrc -Isrc/gl -Isrc/wrappers -g -c -ofsrc/mesh.o src/mesh.d
Internal error: ../ztc/cgcod.c 1464
scons: *** [src/mesh.o] Error 1

Almost. You are right about the bug report system, but there
is a digitalmars.D.bugs newsgroup right next to this one...

Also, your code isn't complete. As Derek showed, the problem is most 
likely caused by what you're not showing. Trunkate the code until you 
have a minimal example showing the behaviour. The lesser snippet, the 
bigger the chance that it's fixed fast.

In my experience, crash bugs are often caused by missing parts in your 
own code (or erranous parts). You should check if your vec3/quat structs 
(classes?) are fully and / or correctly implemented for your use.

I used the simplified test case that Derek compiled succesfully. For me 
it still gives Internal error. (I changed test() to main() and saved to 
  test.d).

test.d:

 struct Pose
 {
    int mTranslate;
    int mRotate;
    int mScale;
    static Pose opCall()
    {
      Pose p;
      p.mTranslate = 1;
      p.mRotate = 2;
      p.mScale = 3;
      return p;
    }
 }

 void main()
 {
    Pose mDefaultPose;
    Pose mCurrentPose;

    mCurrentPose = mDefaultPose = Pose(); // Still ERROR

    mCurrentPose = Pose(); // NO
    mDefaultPose = Pose(); // ERROR
 }



~$ dmd test.d
Internal error: ../ztc/cgcod.c 1464

I am Debian Linux user.

Just wanted to be helpful.
I'll use digitalmars.D.bugs in future...

Not knowing what the 'vec3' and 'quat' etc were, I changed your code to
that below it and compiled okay.  (Windows)

struct Pose
{
   int mTranslate;
   int mRotate;
   int mScale;
   static Pose opCall()
   {
     Pose p;
     p.mTranslate = 1;
     p.mRotate = 2;
     p.mScale = 3;
     return p;
   }
}

void test()
{
   Pose mDefaultPose;
   Pose mCurrentPose;

   mCurrentPose = mDefaultPose = Pose(); // NO! ERROR

   mCurrentPose = Pose(); // NO
   mDefaultPose = Pose(); // ERROR
}
