#19049 [NEW]: Variables go missing suddenly (not register_globals related!)

From: proton@fancreations.com Operating system: Windows XP Home PHP version: 4.2.2 PHP Bug Type: Variables related Bug description: Variables go missing suddenly (not register_globals related!) I have this function I've been using to find a bug in my script, but that now appears to be a bug in PHP itself: function debug($msg) { echo '<b>DEBUG</b>: ' . $msg . '<br/>'; } I have this function on a page with a form on it. When I call this function when the form is not submitted yet, everything goes fine, but when I call it when I have submitted the form, it goes fine a couple of times but then it gives me this message, saying that the variable is undefined: Notice: Undefined variable: msg in f:\website\public_html\test\form.php on line 51 Line 51 is the "echo '<b>'..." line in the function above. I get simillar strange behaviour when I create a new object and then in the object's constructor I access $this and it also gives me an undefined variable error. I get this behaviour with both Apache 2 (2.0.40) and Apache 1 (1.3.26), with PHP versions 4.2.0 and 4.2.2. I haven't tested it on any other versions, but I think it will behave the same. Sometimes Apache 2 crashes on this, other times it would display the errors. After having this a couple of times, my computer even restarts by itself for some reason! Apache 1 always displays the error message. -- Edit bug report at http://bugs.php.net/?id=19049&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19049&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19049&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19049&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19049&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19049&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=19049&r=support Expected behavior: http://bugs.php.net/fix.php?id=19049&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=19049&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=19049&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19049&r=globals
