That's some doggedly determined back tracing to uncover an unexpected heisenbug (loose meaning).

  So a total of 46% of the crashes were due to this rogue force-unload of a DLL. This is a case of bucket spray, where a single underlying cause generates a large number of different types of crashes.

We've not yet seen sufficient evidence this is any type of heisenbug.

It's not, by the article, in a strict taxonomy.

In a wider sloppier sense some use the term for bugs that are hard to pin down and exhibit wide behaviours.

Looking more closely would resolve it one way or the other.
