Customer Impact
There are existing GC related crashes in the wild, that are currently impossible to investigate. A debug option that might assist this is
MONO_GC_DEBUG=check-remset-consistency
, however a customer reported that this option reports false positives. This PR fixes these false positives, hopefully assisting in the investigation of aforementioned GC crashes.Regression
No.
Testing
Manual testing locally.
Risk
Low. This change has no impact unless a certain debug flag is passed, flag which is used for the sole purpose of tracking down GC crashes.
