[Bug c++/28337] New: [4.0/4.1/4.2 regression] ICE with string literals in templates

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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

==============================
template<int> void foo()
{
  (0 ? "" : "X")+1;
}
==============================

bug.cc: In function 'void foo()':
bug.cc:3: internal compiler error: in fold_convert, at fold-const.c:2018
Please submit a full bug report, [etc.]

Without the template or if both string literals have the same length,
the code compiles fine.
