I just want to point out one difference between _PyErr_ChainExceptions and PyErr_SetObject that I encountered while working on this issue: https://bugs.python.org/issue40696 While both functions set the context, only PyErr_SetObject does a check to prevent cycles from forming in the context chain (albeit an incomplete check, which can lead to hangs, which I mention in the issue linked above).
