<<cleanup_point <<< Unknown tree: expr_stmt
  bar (<<< error >>>) >>>>>;

GCC 5.3 produced:
t8932.cc:11:20: error: converting to ‘foo’ from initializer list would use
explicit constructor ‘foo::foo(unsigned int)’
 void bar(foo x = 0u)
                    ^
t8932.cc: In function ‘int main()’:
t8932.cc:18:13: error: converting to ‘foo’ from initializer list would use
explicit constructor ‘foo::foo(unsigned int)’
         bar();
             ^


Confirmed.
