[Bug c++/28711] New: ICE on invalid initializer for multidimensional array

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since at least GCC 2.95.3:

===========================
template<int> struct A
{
  int x[1][1];
  A() : x((int[1][]){{0}}) {}
};

A<0> a;
===========================

bug.cc: In constructor 'A<<anonymous> >::A()':
bug.cc:4: error: multidimensional array must have bounds for all dimensions
except the first
bug.cc: In constructor 'A<<anonymous> >::A() [with int <anonymous> = 0]':
bug.cc:7:   instantiated from here
bug.cc:4: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in tsubst_copy_and_build, at cp/pt.c:9085
Please submit a full bug report, [etc.]
