This is probably the shortest possible: 
-------------- 
template <class T>  void fun_ptr(T (*)()); 
template <class T>  T    bar(); 
 
template <class> void foo () { 
  fun_ptr(bar<int>); 
} 
-------------- 
 
g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ -c x.cc 
 
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc 
x.cc: In function `void foo()': 
x.cc:5: internal compiler error: in resolve_overloaded_unification, at cp/
pt.c:9228

So it's a regression in 3.4/mainline.
