Previous Comments: ------------------------------------------------------------------------ [2011-01-30 11:22:53] s...@php.net Also, please try vc9 build. ------------------------------------------------------------------------ [2011-01-30 10:49:36] s...@php.net Please try using this snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Works fine for me with current SVN 5.3 HEAD. ------------------------------------------------------------------------ [2010-09-08 18:12:46] cataphr...@php.net The problem was the call to floor(). The compiler gave a warning: "d:\users\cataphract\documents\php-trunk\ext\date\lib\interval.c(57) : warning C4013: 'floor' undefined; assuming extern returning int" The assumption is wrong, because it calls double __cdecl floor(_In_ double _X); Which takes and returns a larger type. I removed the call to floor, which is unnecessary since it's an integer division. I also changed the call to abs to a call to llabs to avoid the conversion from long long to int and then to long long again. ------------------------------------------------------------------------ [2010-09-08 18:03:46] cataphr...@php.net The following patch has been added/updated: Patch Name: date_diff Revision: 1283961826 URL: http://bugs.php.net/patch-display.php?bug=52798&patch=date_diff&revision=1283961826 ------------------------------------------------------------------------ [2010-09-08 17:36:02] cataphr...@php.net I can reproduce only on Windows. The exactly value varies (seems to be garbage memory). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
