[Bug c++/16714] New: ICE with typeof() involved

[marco at technoboredom dot net]

This code produces an ICE with gcc-3.4.1/linux: 

/* BEGIN */
template<class T>
struct W  { };
 
template<class X, class Y>
W< typeof(X()+Y()) > operator + (W<X> x, W<Y> y);  

int fail() 
{
  W<int> wx,wy; 
  wx=wx+wy; 
}
/*END */
The error message is: 
marco@gontscharow:~/tmp/gcc$ /opt/gcc-3.4.1/bin/g++ -c a.cc
a.cc: In function `int fail()':
a.cc:10: internal compiler error: in write_type, at cp/mangle.c:1566
