Description Martin Kronbichler 2011-03-17 12:41:11 UTC 
Using gcc version 4.6.0 20110317 (svn revision 171087) on x86-64 Linux with the code

struct foo {
  static void func ();
};
void foo::func () const {};

and compile line "g++ -c test_static.cc" gives the following:

test_static.cc:4:19: internal compiler error: in merge_types, at cp/typeck.c:825
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

The code is clearly invalid (g++ 4.5 indeed gives the following error message: "test_static.cc:4:19: error: static member function ‘void foo::func()’ declared with type qualifiers"), but g++ 4.6 returns with an ICE.
