Hi all,
I am writting a code with Coroutines lib, this code uses coroutines in a recursive way but when I create a large number of coroutines the program crashes (segmentation fault). I write a simplified version that reproduces this error:

#include<iostream>
#include<cstdlib>
#include<boost/coroutine/all.hpp>
#include <boost/bind.hpp>
#include <boost/shared_ptr.hpp>

class FClass{
    private:
        int n;
    public:
        boost::coroutines::coroutine<void>::pull_type* startResume;
        FClass(int n) : n(n){
            startResume = NULL;
        }
        void resume(){
            if(startResume && *(startResume))
                (*(startResume))();
        }
        void doSomething ( boost::coroutines::coroutine< void >::push_type & fPause){
            if (n > 2){
                FClass* tc1 = new FClass(--n);
                tc1->startResume = new boost::coroutines::coroutine<void>::pull_type( boost::bind( &FClass::doSomething, tc1, _1)  );

                FClass* tc2 = new FClass(--n);
                tc2->startResume = new boost::coroutines::coroutine<void>::pull_type( boost::bind( &FClass::doSomething, tc2, _1)  );

                fPause();

                tc1->resume();
                tc2->resume();
            }
            return;
        }
};

int main(int argc, char** argv){

    int max = 10;
    if (argc > 1){
        max = atoi(argv[1]);
    }

    FClass* firstObject = new FClass (max)  ;
    firstObject->startResume = new boost::coroutines::coroutine<void>::pull_type( boost::bind(&FClass::doSomething, firstObject, _1)  );

    firstObject->resume();

}


gdb output reports:"memset () at ../sysdeps/x86_64/memset.S:78  ../sysdeps/x86_64/memset.S:No such file or directory."

Anybody can help me?

Regards,
Van
