I got a Serious problem，here is the nginx config:

nginx version: nginx/0.8.55  
built by gcc 4.1.2 20080704 (Red Hat 4.1.2-52)  
TLS SNI support enabled  
configure arguments: --user=www --group=www --prefix=/data/nginx/  
–with-google\_perftools\_module --with-http\_stub\_status\_module  
–with-openssl=/usr/local/openssl-1.0.1c --with-http\_gzip\_static\_module  
–with-http\_ssl\_module

and here is the error message:

\*\*\* glibc detected \*\*\* nginx: master process /data/nginx/sbin/nginx -c  
/data/nginx/conf/nginx.conf: free(): invalid pointer: 0x00000000005b9980
