Bug #73954 [NEW]: NAN check fails on Alpine Linux with musl

From: zaq178miami at gmail dot com Operating system: Alpine Linux PHP version: Irrelevant Package: *General Issues Bug Type: Bug Bug description:NAN check fails on Alpine Linux with musl Description: ------------ It seems to be that is_nan check fails or sth like that as when passing NAN to as an int parameter it silently casted to int(0). While int(0) is valid result for explicit (int)NAN cast, according to Andrea (https://wiki.php.net/rfc/zpp_fail_on_overflow). As already discussed on SO (http://chat.stackoverflow.com/transcript/message/35136128#35136128) it might be just a musl bug, but maybe we should check what NAN do we have and maybe alter config scripts and/or php_get_nan() accordingly? Here is runnable snippet: https://3v4l.org/m7hpq Test script: --------------- <?php function test(int $test) { var_dump($test); } test(NAN); Expected result: ---------------- Fatal error: Uncaught TypeError: Argument 1 passed to test() must be of the type integer, float given, called in /in/m7hpq on line 6 and defined in /in/m7hpq:2 Stack trace: #0 /in/m7hpq(6): test(NAN) #1 {main} thrown in /in/m7hpq on line 2 Actual result: -------------- int(0) -- Edit bug report at https://bugs.php.net/bug.php?id=73954&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73954&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73954&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73954&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73954&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73954&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73954&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73954&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73954&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73954&r=support Expected behavior: https://bugs.php.net/fix.php?id=73954&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73954&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73954&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73954&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73954&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73954&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73954&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73954&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73954&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73954&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73954&r=mysqlcfg
