--- Comment #4 from pivanov at hotmail dot com --- It really looks like endless recursion as the whole memory gets exhausted if I leave it running long enough. What I see in bug 106617 description (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106617) is that it just works slowly but gets the work done.
