Previous Comments: ------------------------------------------------------------------------ [2009-10-23 15:19:45] php dot vope at gishpuppy dot com Description: ------------ The PHPT test ext\filter\046.phpt fails when run on a 64-bit system. The problem is likely to be that ~(PHP_INT_MAX)-1 is not sufficient to create an underflow on 64-bit. This is because a float on 64-bit has less bits than an integer ( since it needs some for the exponent ). The test would pass if ~(PHP_INT_MAX)-2000 was used instead. On 64-bit ~(PHP_INT_MAX)-2000 = float(-9223372036854777856) which would be enough of a difference to make the test valid.
