Bug #52678 [NEW]: Segmentation fault on scripts execution

From: Operating system: Solaris 5.10, Spark PHP version: 5.3.3 Package: Reproducible crash Bug Type: Bug Bug description:Segmentation fault on scripts execution Description: ------------ Reading bug reports I've seen #47230, similar, near one year ago. Apparently there is a problem with memory alignment. I used gcc 4.2.3 and make 3.81 from gcc installation. Non of system script in CL mode can be executed. In my example script, when commentting out 'sleep()', there is no crash. - version --------------------------------------------------------------- bash-3.2$ sapi/cli/php --version PHP 5.3.3 (cli) (built: Aug 20 2010 07:45:05) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies - phpinfo() ------------------------------------------------------------- System => SunOS csdev10 5.10 Generic_142900-02 sun4u Build Date => Aug 20 2010 07:40:16 Configure Command => './configure' '--without-iconv' '--disable-phar' Server API => Command Line Interface Virtual Directory Support => disabled Configuration File (php.ini) Path => /usr/local/lib Loaded Configuration File => (none) Scan this dir for additional .ini files => (none) Additional .ini files parsed => (none) PHP API => 20090626 PHP Extension => 20090626 Zend Extension => 220090626 Zend Extension Build => API220090626,NTS PHP Extension Build => API20090626,NTS Debug Build => no Thread Safety => disabled Zend Memory Manager => enabled Zend Multibyte Support => disabled Test script: --------------- <?php echo "One\n"; sleep(1); echo "Two\n"; ?> Expected result: ---------------- Text output: 'One, Two'.
