D.gnu - [Bug 279] New: ICE in local class definition.


            Bug ID: 279
           Summary: ICE in local class definition.
           Product: GDC
           Version: development
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gdc
          Assignee: ibuclaw gdcproject.org
          Reporter: dorian.haglund gmail.com

The following code fails to compile with gdc (Debian 7.2.0-12) 7.2.1 20171025.

struct S (T)

  T t;

int main()
  class C
    S!C member;

  return 0;

  /home/dorian/dev/lib_algo 0 % gdc mini.d

cc1d: ../../src/gcc/d/dfrontend/optimize.c:628: virtual void
Expression_optimize(Expression*, int, bool)::OptimizeVisitor::visit(CastExp*):
Assertion `cdfrom->sizeok == SIZEOKdone' failed.
cc1d: internal compiler error: Aborted
Please submit a full bug report,
with preprocessed source if appropriate.

About my box:
  /home/dorian/dev/lib_algo 1 % uname -a                                        
Linux allegro75 4.13.0-1-amd64 #1 SMP Debian 4.13.4-2 (2017-10-15) x86_64

The code compiles if the class C definition is moved outside the main's scope.

The code compiles if 'S!C' is replaced by 'S!int'. (A self referencing issue?)

The code compiles if the struct 'S' doesn't have a 'T' member.

The code compiles as is with dmd and ldc.
