My understanding is that CWG 1473 clarified this:

            Bug ID: 60226
           Summary: ICE initializing array of elements with too large
                    alignment
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Keywords: error-recovery, ice-on-invalid-code
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following invalid code snippet triggers an ICE since GCC 4.0.0:

======================================================typedef int __attribute__ ((aligned(1 << 28))) int28;
int28 foo[4] = {};
======================================================
bug.c:2:1: error: alignment of array elements is greater than element size
 int28 foo[4] = {};
