Bug #69803 [NEW]: gmp_random_range() modifies second parameter if GMP number

From: andy dot shawaluk at pkware dot com Operating system: Windows 7 PHP version: master-Git-2015-06-11 (snap) Package: GNU MP related Bug Type: Bug Bug description:gmp_random_range() modifies second parameter if GMP number Description: ------------ When calling the gmp_random_range($min,$max) function where $max is a GMP number, the value of $max is modified - after the function returns, it is reduced by ($min-1). If $max is an ordinary integer (as shown in the online help page), this does not happen.

Revision: r7ec3016 (June 09 2015, 17:20:07) Test script: --------------- <?php $a = gmp_init('100'); $b = gmp_init('200'); echo gmp_strval($a) .", ". gmp_strval($b) ."\n"; $c = gmp_random_range($a, $b); echo gmp_strval($a) .", ". gmp_strval($b) ." -> ". gmp_strval($c) ."\n"; Expected result: ---------------- 100, 200 100, 200 -> [number between 100 and 200 inclusive] Actual result: -------------- 100, 200 100, 101 -> [number between 100 and 200 inclusive] -- Edit bug report at https://bugs.php.net/bug.php?id=69803&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69803&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69803&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69803&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69803&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69803&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69803&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69803&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69803&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69803&r=support Expected behavior: https://bugs.php.net/fix.php?id=69803&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69803&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69803&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69803&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69803&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69803&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69803&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69803&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69803&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69803&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69803&r=mysqlcfg
