[Bug c++/34936] New: [4.3 regression] ICE with double and attribute may_alias

["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 3.3:

============================================
typedef double X __attribute((may_alias)) ;

template<typename> struct A
{
  A();
};

A<X> a;
============================================

bug.cc: In function 'void __static_initialization_and_destruction_0(int, int)':
bug.cc:8: internal compiler error: in write_builtin_type, at cp/mangle.c:1849
Please submit a full bug report, [etc.]

The code compiles if I use char or int instead of double.
