Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aldyh at gcc dot gnu.org, | |amacleod at redhat dot com Keywords| |ice-on-valid-code --- 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).
