http://issues.apache.org/bugzilla/show_bug.cgi?id=36234 Summary: certain VirtualHost directives in httpd.conf cause httpd -S to core in dump_a_vhost Product: Apache httpd-2.0 Version: 2.0.54 Platform: Sun OS/Version: Solaris Status: NEW Severity: normal Priority: P2 Component: mod_vhost_alias AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] The following configuration causes a seg fault on Solaris 10 (sparc): --cut-- NameVirtualHost *:80 <VirtualHost *> ServerName adminconsole.test.com DocumentRoot /opt/apache2/htdocs ErrorLog logs/adminconsole.test.com-error_log CustomLog logs/adminconsole.test.com-access_log common </VirtualHost> <VirtualHost *> ServerName control.test.com DocumentRoot /opt/apache2/htdocs ErrorLog logs/control.test.com-error_log CustomLog logs/control.test.com-access_log common </VirtualHost> --cut-- Some playing with the above configuration proves that it is only the last <VirtualHost *> entry that causes the core. If <VirtualHost *:80>, or <VirutalHost hostname> is used for the last entry everything works as expected if using <VirtualHost *> in prior declarations. Here is a truss and map of the core: --cut-- [EMAIL PROTECTED] {SunOS 5.10} - (via 192.168.52.88)] [507] /opt/apache2/conf 7 truss /opt/apache2/bin/httpd -S --snip-- stat("/opt/apache2/htdocs", 0xFFBFF378) = 0 VirtualHost configuration: write(2, " V i r t u a l H o s t ".., 27) = 27 wildcard NameVirtualHosts and _default_ servers: write(2, " w i l d c a r d N a m".., 49) = 49 *:* adminconsole.test.com (/opt/apache2/conf/httpd.conf:252) write(2, " * : * ".., 80) = 80 *:* control.test.com (/opt/apache2/conf/httpd.conf:259) write(2, " * : * ".., 75) = 75 Incurred fault #6, FLTBOUNDS %pc = 0x000364C4 siginfo: SIGSEGV SEGV_MAPERR addr=0x0000000C Received signal #11, SIGSEGV [default] siginfo: SIGSEGV SEGV_MAPERR addr=0x0000000C --cut-- --cut-- [EMAIL PROTECTED] {SunOS 5.10} -
