[Bug c++/42083] New: [C++0x] ICE on invalid with "tree check: expected aggr_init_expr, have error_mark in build_value_init"

["lloyd at randombit dot net" <gcc-bugzilla at gcc dot gnu dot org>]

This code (in includes needed) ICEs with GCC 4.5 20091112

template<typename F>
decltype(F()) run(F f)
   {
   return f();
   }

int main()
   {
   auto l = []() { return 5; };

   run(l);
   }

Compiler output:

$ g++-4.5-20091112 -std=c++0x decl.cpp -o decl
decl.cpp: In function 'int main()':
decl.cpp:14:9: error: no matching function for call to
