--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
It looks like ranger initializes a few bitmap obstacks, if there's no
convenient
ranger-wide one then calling

bitmap_obstack_initialize (NULL);

from enable_ranger and

bitmap_obstack_release (NULL);

from disable_ranger would initialize the global one (those handle nesting
from other callers).
