          Issue ID: 13225
           Summary: [ICE] Access violation on invalid mixin template
                    instantiation
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Windows
            Status: NEW
          Severity: major
          Priority: P1
         Component: DMD
          Assignee: nobody at puremagic.com
          Reporter: jblume at jblume.com

mixin template M(T)
{
}

struct S
{
    mixin M!((typeof(this)) => 0);
    mixin M!(() => undefined);
}


With v2.066.0-b6 running on Windows this leads to:

main.d(8): Error: undefined identifier undefined
Unhandled exception at 0x00439BF1 in dmd.exe: 0xC0000005: Access violation
reading location 0x00000029.

Removing one of the mixins or replacing "undefined" with a literal works.
