Doc #65852 [NEW]: Fileinfo file() method and any mp3 file crashes php.

From: chalkerx at gmail dot com Operating system: Linux PHP version: 5.5.4 Package: Documentation problem Bug Type: Documentation Problem Bug description:Fileinfo file() method and any mp3 file crashes php. Description: ------------ http://www.php.net/manual/en/types.comparisons.php states: > Some numeric operations can result in a value represented by the constant NAN. Any loose or strict comparisons of this value against any other value, including itself, will have a result of FALSE But that is invalid, because NAN loosely equals to boolean true. Test script: --------------- var_dump(sqrt(-1)); var_dump(sqrt(-1) == true); Expected result: ---------------- As per documentation, the result should be: double(NAN) bool(false) The documentation should be consistent with what actually happens. Actual result: -------------- double(NAN) bool(true) -- Edit bug report at https://bugs.php.net/bug.php?id=65852&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65852&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=65852&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65852&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65852&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65852&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65852&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65852&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65852&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65852&r=support Expected behavior: https://bugs.php.net/fix.php?id=65852&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65852&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65852&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65852&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65852&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65852&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65852&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65852&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65852&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65852&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65852&r=mysqlcfg
