The tests are also pass now, the doc is wrong. ------------------------------------------------------------------------ [2012-04-05 21:21:07] mattficken@php.net Description: ------------ 022.phpt which tests gmp_gcdext() and gmp_nextprime.phpt which tests gmp_nextprime() fail on Windows but pass on Linux. The returned value of both of those functions in some cases doesn’t match the expected value(in some cases it does). In example #1 in the documentation for gmp_nextprime() (http://us3.php.net/gmp_nextprime), gmp_nextprime(-1000) returns -997 however on Linux it returns 2, which is what the test expects so the test passes. Not only is this a behavior difference between Windows and Linux but is not what the documentation states ( gmp_nextprime(-1000) => -997 not 2). ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61643&edit=1
