| Description | Configura report a problem using mps_arena_unsafe_expose_remember_protection [1]. A fatal assert when mps_arena_unsafe_restore_protection. |
| Analysis | Turns out we are using the wrong test when deciding what segs to remember. PoolMRG has AttrSCAN but does not use GCSegClass. only GCSegClass segments are legal to use with SegSummary. |
