    [heap] Filter slots in map space · 23f61424
    mlippautz authored
    We mark an object allocated as uninitialized. If we happen to have a GC before
    fields of a map are written, msan will observe access to unitialized memory and
    crash.
    
    This also unifies the handling as we now deal with all spaces in the same way.
    In future we could parallelize clearing.
