[New-bugs-announce] [issue28069] signalmodule.c does "is" comparisons for SIG_IGN and SIG_DFL

[Mark Dickinson]

New submission from Mark Dickinson:

Modules/signalmodule.c contains this code:

    if (handler == IgnoreHandler)
        func = SIG_IGN;
    else if (handler == DefaultHandler)
        func = SIG_DFL;
    ...

Here IgnoreHandler and DefaultHandler are ints. The code above effectively does an "is" comparison with those ints, assuming that SIG_IGN and SIG_DFL are amongst the small interned ints.
