Possibly this was used MiniDumpFilterTriage (from https://learn.microsoft.com/en-us/windows/win32/api/minidump...) and some of other stripping/scrubbing data fields.

This one fills all non-null ptr in the callstack (and other areas?) with 0xAAAAAAAA

I actually had to fix this for us two weeks ago, as our internal tools were crashing on the CI with this, and it wasn't helpful (to us), but at the same time understand how important is for this if shipped to external customers.

Crashdumps are underrated field that needs more eyes to solve the big data problem there.
