[Cppcms-users] Segmentation fault

[Mario P. <mp...@us...>]

Hello,

I'm starting to use CppCMS ("cppcms-0.99.3.tar.bz2" downloaded from 
SourceForge), and noticed that when generating very long responses, the 
executable ends with a segfault. I am using the built-in server, and I reduced 
the code to the following:

______________________________________________________________________________
/*
   bench.cpp
*/
#include <cppcms/application.h>
#include <cppcms/applications_pool.h>
#include <cppcms/service.h>
#include <cppcms/http_response.h>
#include <iostream>

class bench : public cppcms::application
{
public:
   bench(cppcms::service &srv) : cppcms::application(srv) { }

   virtual void main(std::string url)
   {
     for (int i=0; i < 100000; ++i) {
       response().out() << i << "\n";
     }
   }//main
};//class bench

int main(int argc, char *argv[])
{
   try {
     cppcms::service srv(argc, argv);
     srv.applications_pool().mount(cppcms::applications_factory<bench>());
     srv.run();
   }
   catch (const std::exception &e) {
     std::cerr << e.what() << std::endl;
   }

   return 0;
}//main
______________________________________________________________________________

______________________________________________________________________________
/*
   config.js
*/
{
   "service": {
     "api": "http",
     "port": 8080,
   },
   "http": {
     "script_names": [ "/bench" ],
   },
}
______________________________________________________________________________


I start the application:

   $ ./bench -c config.js

Then, I use "curl" to make a request:

   $ curl http://localhost:8080/bench

And the application ("bench") terminates with a segmentation fault.

A backtrace shows that the last statement that is executed is the line 476 of 
file "cgi_api.cpp" ('write_some()' in function 'connection::write()'), but so 
far I have not gotten more information.

Can anyone else reproduce the problem? Can be solved if I use the latest 
version in SVN? (I'll try to test soon with the latest version of the code).

Thank you for creating something as awesome as CppCMS. Regards,

Mario
