[New-bugs-announce] [issue20941] pytime.c:184 and pytime.c:218: runtime error, outside the range of representable values of type 'long'

[Jeffrey Walton]

New submission from Jeffrey Walton:

pytime.c:184: runtime error: value -1e+200 is outside the range of representable values of type 'long'

   and

pytime.c:218: runtime error: value -1e+200 is outside the range of representable values of type 'long'

It appears the cast on 'intpart' is generating the finding. 'intpart' is a double.

    *sec = (time_t)intpart;
    err = intpart - (double)*sec;
    if (err <= -1.0 || err >= 1.0) {
        error_time_t_overflow();
        return -1;
    }

Shouldn't a range test based on TIME_T_MAX with an epsilon occur first?
