If it helps, I have written an equivalent asynchronous application, and the 
error does NOT occur:

______________________________________________________________________________
/*
    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";
     }
     release_context()->async_complete_response();
   }//main
};//class bench

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

   return 0;
}//main

When do you recommend using an application of one type or the other?

Best regards,
