#44981 [Opn->Fbk]: If script contains a function declaration and dl() fails -> segfault

ID: 44981 Updated by: jani@php.net Reported By: mabouzou at sybase dot com -Status: Open +Status: Feedback Bug Type: Reproducible crash Operating System: * PHP Version: 5.2.6 New Comment: 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 Previous Comments: ------------------------------------------------------------------------ [2008-05-13 14:12:34] mabouzou at sybase dot com I forgot to mention that the extension library has to define at least one function in the zend_function_entry table. Also, if the library is loaded from the ini file directly the crash does not happen. ------------------------------------------------------------------------ [2008-05-13 13:57:47] mabouzou at sybase dot com Description: ------------ PHP would crash while executing the attached code. The code basically declares a function and attempts to load an extension using the dl() command. If the extension returns FAILURE in the MINIT function, PHP will crash. Reproduce code: --------------- <?php function foo() { echo "Inside foo.\n"; } dl( 'my_extension.dll' ); ?> Expected result: ---------------- Inside foo. <... something along the lines of ... cannot load extension my_extension.dll ... > Actual result: -------------- A crash.
