    [heap] Add large_object_threshold to AllocateRaw · 71736859
    Daniel Bevenius authored
    This commit adds a check in Heap::AllocateRaw when setting the
    large_object variable, when the AllocationType is of type kCode, to
    take into account the size of the CodeSpace's area size.
    
    The motivation for this change is that without this check it is
    possible that size_in_bytes is less than 128, and hence not considered
    a large object, but it might be larger than the available space
    in code_space->AreaSize(), which will cause the object to be created
    in the CodeLargeObjectSpace. This will later cause a segmentation fault
    when calling the following chain of functions:
    
       if (!large_object) {
          MemoryChunk::FromHeapObject(heap_object)
              ->GetCodeObjectRegistry()
              ->RegisterNewlyAllocatedCodeObject(heap_object.address());
       }
    
    We (Red Hat) ran into this issue when running Node.js v12.16.1 in
    combination with yarn on aarch64 (this was the only architecture that
    this happed on).
