I don't think your reproducer is 100% reliable.
And bisection is great because it's very aggressive and optimal when it comes to testing. But that also implies that if *any* of the good/bad choices were incorrect, then the end result is pure garbage and isn't even *close* to the right commit.

So have you actually been able to see the problem with FLATMEM, or is this based on the bisect? Because I really think the bisect is pretty much guaranteed to be wrong.
