2 weeks ago I ran this against another heap dump that I took and wasn't able to reproduce the issue 🤔
Not sure why the first heap dump I took would cause this; while the other doesn't. If you can point me in correct place to look I can check if this is something wrong with my heap dump or if it's common to flamegraph.pl.
But otherwise maybe this can just be closed.
I'm not entirely sure the preconditions; but I've been doing some work on visualizing heaps from a couple of formats.

I'm a little confused as to what's causing this because my other implementations are very similar; but the issue only occurs with this implementation. Perhaps it's due to having such a large amount of small allocations? Is this a known issue?
Originally I thought it might be due to missing frames between the root node and leafs.
ie:

But after making sure that I properly create a full tree of my heap (including frames without allocations) I still was able to reproduce.
