--- Comment #38 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
Hmm...

the whole thing goes kaboom if I try to call any of the procedures in
recursive_interface_2.f90.

i.e. if I add the following at the end of the test case:

use m
  procedure(foo), pointer :: p_foo
  procedure(bar), pointer :: p_bar
  procedure(baz), pointer :: p_baz
  p_foo => foo
  p_bar => bar
  p_baz => baz
  call foo (p_foo)
  call baz (p_bar)
  call bar (p_baz)
  call p_foo (p_foo)
  call p_baz (p_bar)
  call p_bar (p_baz)
end
