// Test for catching infinitely recursive instantiations.
// Origin: Jason Merrill <[e-mail]>

// Special g++ Options: -ftemplate-depth-10

template <int i> void f()
{
  f<i+1>();			// ERROR - excessive recursion
}

// We should never need this specialization because we should issue an
// error first about the recursive template instantions.  But, in case
// the compiler fails to catch the error, this will keep it from
// running forever instantiating more and more templates.
