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.
