Current trunk (as well as the whole 4.2 branch, it seems), ICEs on the
following invalid code:
module foo
type bar
logical, pointer, dimension(:) :: baz
end type
contains
function func1()
type(bar) func1
allocate(func1%baz(1))
end function
function func2()
type(bar) func2
allocate(func1%baz(1))
end function
end module foo
