Thanks for the patch. I applied it and the problem is gone. Excellent!




Below, I am describing my setup for nginx and FastCGI / CGI C++ Librarym
in case someone is interested.

Step 1
nginx.conf
http {
...
  server {
  ...
     location ~ \.toff$ {
       include /usr/local/nginx/conf/fastcgi.conf;
       fastcgi_pass 127.0.0.1:9000;
     }
}
location is written that way because it so happens that all my fasctgi app
have an .toff extension

Step 2
Since nginx does not serve cgi scripts, it is up to the developer to find
a way to have nginx and the CGI app. I am using supervisord, which is "a
client/server system that allows its users to control a number of
processes on UNIX-like operating systems" (see supervisord.org).

/etc/supervisord.conf
...
    131 [fcgi-program:chat]
    132 command=/path/chat.toff
    133 socket=tcp://127.0.0.1:9000
    134 process_name=%(program_name)s_%(process_num)02d
    135 numprocs=1
    136 priority=999
    137 autostart=true
    138 autorestart=unexpected
    139 startsecs=1
    140 startretries=3
    141 exitcodes=0,2
    142 stopsignal=QUIT
    143 stopwaitsecs=10

Step 3
to compile a FastCGI / CGI C++ Library, I do the following:
g++ -Wall ...
supervisorctl restart chat:*
