           Summary: Compiler crash or unstable code generation with scoped
                    interface instances
           Product: D
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Keywords: ice-on-valid-code
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: jason.james.house at gmail.com


The bottom of this post contains code that reproduces the problem.

It's known to cause issues with the following conditions:
dmd 1.018, windows, tango
dmd 1.023, linux, tango

It's known to not cause issues with the following conditions:
dmd 1.023, linux, phobos
dmd 1.024, ???, phobos
gdc 0.24, linux, tango
gdc 0.24, linux-64, phobos

It looks to be specific to the combination of dmd and tango.  It has not been
tested with dmd 2.x.
