Thanks, I find which changes cause it. After I revert the change about InterpreterOnStackReplacementDescriptor and BaselineOnStackReplacementDescriptor merge into OnStackReplacementDescriptor(https://paste.ubuntu.com/p/hRzqXHB9rJ/), the issue 13836 <https://bugs.chromium.org/p/v8/issues/detail?id=13836> is fixed. But it is not a root reason. According to my understanding, OnStackReplacementDescriptor is the same as InterpreterOnStackReplacementDescriptor and BaselineOnStackReplacementDescriptor. This change doesn't change anything.
