To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2007-10-24 22:33:59] [EMAIL PROTECTED] Tested it on 5.2-dev and 6.0-dev snapshots, incorrect behavior is same on both. ------------------------------------------------------------------------ [2007-10-24 08:41:13] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows (zip): http://snaps.php.net/win32/php5.2-win32-latest.zip For Windows (installer): http://snaps.php.net/win32/php5.2-win32-installer-latest.msi ------------------------------------------------------------------------ [2007-10-24 03:55:16] [EMAIL PROTECTED] Description: ------------ I don't know what to make of this behavior. When CURL creates a handle with 32 characters or more to the local filesystem, duplicates it, and then PHP attempts to create a new object while passing in a parameter that is an array of values, PHP crashes. I could only produce this behavior on Windows Vista. Reproduce code: --------------- <?php // for Windows Vista, PHP 5.2.4 class foo { function __construct($var) {} } curl_copy_handle(curl_init('12345678901234567890123456789012')); // 32 or longer new foo(array('foo')); echo 'Yay!'; Expected result: ---------------- Output of 'Yay!' Actual result: -------------- PHP aborts prematurely ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43092&edit=1
