decimal: Context(traps=...) dereferences a SignalDict's NULL flags pointer #161389
Description
Bug report
Summary
Building a Context from a signal dictionary that you created yourself crashes the interpreter with seg fault.
Expected: the same NULL check the signal-dict methods already make, or a ValueError.

import decimal
SignalDict = type(decimal.Context().traps)
