--- Comment #14 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I can confirm the analysis, except that I see the edge we're trying to
add to the heap as already inlined (as a speculative edge it got
inlined even its caller was).  Also just not adding an edge with
non-NULL aux works for me - and at least I cannot think of anything
smarter, I guess the inliner has to figure out it has already dealt
with it.

If it indeed can cause an assert failure in
estimate_calls_size_and_time then I think we simply we need to force
it not to "use_table" when it next comes around to the caller.
