nginx+fastcgi出现worker process 1297 exited on signal 11

[u013682998]

各位大神，请帮小弟看看下面的问题：
我使用Nginx服务器+fastcgi，运行cgi程序，nginx一直提示：worker process 1297 exited on signal 11
使用gdb跟踪，发现如下：
(gdb) c
Continuing.

Program received signal SIGSEGV, Segmentation fault.

如果不调用cgi程序而运行html程序，则一切正常，下面是我的nginx.conf文件：
#user nobody;
user nobody nobody;

#same as cpu num;
worker_processes 1;

error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#error_log /var/log/nginx/error.log;

pid logs/nginx.pid;
#pid /var/run/nginx.pid;

#same as "ulimit -n"

#use epoll;

}

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root /var/www;
index login.cgi;
#allow 192.168.50.0/24;
#deny all;
}

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/www/;
}

# proxy the CGI scripts to Nginx listening on 127.0.0.1:9000
#
location ~ .*\.cgi$ {
root /var/www/;
gzip off;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.cgi;
include fastcgi.conf;
}
}
}

下面是启动fastcgi命令：
/var/nginx/bin/spawn-fcgi -f /var/nginx/sbin/fcgiwrap -a 127.0.0.1 -p 9000 -F 2 -P /tmp/fastcgi-c.pid -u nobody -g nobody

请各位大神帮忙分析下，谢谢了

SIGSEGV are u sure your cgi script is bug free?

[u013682998]

index.cgi内容如下： #!/bin/sh echo Content-type: text/html echo "" echo Hello, world.
