    Prevent stack frame cache usage during isolate serialization · dec6dc4b
    Simon Zünd authored
    Individual frames of a stack frame in the frame cache might point
    to the JSFunction of that corresponding stack frame. It is illegal to
    serialize JSFunction objects in the isolate snapshot, so the attempt
    to serialize the stack frame cache results in a crash. This can happen
    when a warmup script is run, before a snapshot is created.
    
    This CL fixes the crash by not utilizing the stack frame cache in case
    the serializer is enabled.
