           Summary: Assertion failure: 'd' on line 4234 in file 'mtype.c' on
                    faulty d code
           Product: D
           Version: 1.020
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: sky@quit-clan.de


The compiler crashes when i try to compile the following faulty d code:
-------
struct ABC()
{
    alias NonExistentTemplate!() y;
}

void main()
{
    auto abc = new ABC!();
    foreach (x; abc.y) {} // Required for the compiler to crash
}
-------

The output of the compiler is:
-------
ass4234.d(3): template instance identifier 'NonExistentTemplate' is not defined
ass4234.d(8): template instance ass4234.ABC!() error instantiating
Assertion failure: 'd' on line 4234 in file 'mtype.c'

abnormal program termination
-------

It does, however, not crash if you don't use a template in the template ABC or if you comment out the foreach loop. This bug is uncritical for development because the compiler actually shows all the errors before crashing...

------- Comment #1 from ddparnell@bigpond.com  2007-10-19 02:20 -------
The following code also crashes with the same "Assertion failure" message.
----
struct X
{
  import std.stdio;
}
void main()
{
   X.std.stdio.writefln("");
}
----

However the following code compiles and runs ...
----
struct X
{
  import std.stdio;
}
void main()
{
   X.writefln("");
}
----

Can we close this one? 

It looks like a dupe of #1783 and that was closed by 1.026

The error message now gives is slightly different to this title. Closing this bug and re-opened as BUG 2489.
