Comment:
Thanks for a great bug report. The code is now:
{{{
// Avoid overflow when we multiply seconds by 1000. See #2848
return (lnat)((StgWord64)tv.tv_sec * 1000 / interval +
(StgWord64)tv.tv_usec / (interval * 1000));
}}}
fixed by this patch:
{{{
Tue Dec 9 10:56:00 GMT 2008 Simon Marlow <[EMAIL PROTECTED]>
* Fix #2848: avoid overflow during time calculation
}}}
