[Bug c++/27385] New: [4.1/4.2 regression] ICE with invalid array initializer

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE since GCC 4.1.0
(and in GCC 3.3, 3.3.1, 3.3.2):

========================
struct A {};

A a[] = { 0 };
========================

The compiler loops forever until it runs out of memory:
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
bug.cc:3: error: initializer for 'A' must be brace-enclosed
[etc.]
