When tried to access SugarCRM 6.5.13 after installation following error showed up in browser:
CRASH: PHP segmentation violation in session_start() called at [/install.php:486]
To fix that issue .htaccess file has to be created in SugarCRM main older with following content:
# BEGIN SUGARCRM RESTRICTIONS RedirectMatch 403 (?i)^.*\.log$ RedirectMatch 403 (?i)/+not_imported_.*\.txt RedirectMatch 403 (?i)/+(soap|cache|xtemplate|data|examples|include|log4php|metadata|modules)/+.*\.(php|tpl) RedirectMatch 403 (?i)/+emailmandelivery\.php RedirectMatch 403 (?i)/+cache/+upload # END SUGARCRM RESTRICTIONS
