#19429 [NEW]: Using $GLOBALS in the global variable scope causes a segmentation fault

From: dragon@wastelands.net Operating system: Slackware Linux 2.4.5 PHP version: 4.2.2 PHP Bug Type: Reproducible crash Bug description: Using $GLOBALS in the global variable scope causes a segmentation fault I typically write my code on a local machine running 4.1.2. The following code works fine on my local machine, but causes a segmentation fault in the apache child sending the page, which is on the server using 4.2.2. The offending line was: foreach ($vars as $var) if ($GLOBALS["$var"]) { $prosql = 1; $websql = 1; } Obviously it is quite stupid trying to access global variables like this from within the global scope, but this line got moved from a function at some stage and obviously I didn't change it. Anyways -- stupid code shouldn't crash the server. and it took me long enough to even find the offending line. changing the middle part to "if ($var)" promptly fixed the problem. -- Edit bug report at http://bugs.php.net/?id=19429&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19429&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19429&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19429&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19429&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19429&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=19429&r=support Expected behavior: http://bugs.php.net/fix.php?id=19429&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=19429&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=19429&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19429&r=globals
