[Bug c++/29979] New: ICE with vector types in templates

[reichelt at gcc dot gnu dot org]

The following code snippet triggers an ICE since GCC 3.3:

===================================================
template<typename T> struct A
{
  static const T i = 1;
  int __attribute__((vector_size(8))) a[i];
};
===================================================

bug.cc:4: internal compiler error: in fold_convert, at fold-const.c:2066
Please submit a full bug report, [etc.]


A similar code snippet triggers a segfault:

===================================================
template<typename T> struct A
{
  int __attribute__((vector_size(8))) a[T::i];
};
===================================================

bug.cc:3: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
