Comment (by kevin8t8):
One fix would be to add an additional range check in mutt_mktime() below
the TM_YEAR_MAX check. Something like:
{{{
/* 64-bit platforms can theoretically hold a very large year, but other
system
* calls such as strftime() and gmtime() error out on large year values.
* Cap the value at year 9999.
*/
if (t->tm_year > 9999-1900)
t->tm_year = 9999-1900;
}}}
I think the TM_YEAR_MAX check is still needed for 32-bit time_t platforms,
so this would be in addition.
I believe this would also "fix" #3989 although I think we should still add
a NULL check there for correctness.
