SystemC 2.3.3: huge memory consumption when using sc_spawn - sc_bind

Recommended Posts

Hello,

I've noticed that with SystemC 2.3.3, when I spawn a dynamic process, there is a huge memory consumption.

Here' s the code generating the problem

#include "test_module.h"

void test_module::my_process(int temp) {
    printf("thread spwned @ %.1f\n",sc_simulation_time());
    wait(1000,SC_NS);
}

void test_module::test_thread(void) {
    int temp=0;
    while(true) {
        printf("current time is %.1f\n",sc_simulation_time());
        if (sc_simulation_time()>=100000000) {
            printf("stop here\n");
            wait();
            sc_stop();
        }
        else {
            sc_spawn_options my_thread;
            sc_process_handle test_proc;
            my_thread.set_sensitivity(&clock.pos());
            test_proc = sc_spawn(sc_bind(&test_module::my_process,this,temp),NULL,&my_thread);
            wait(10,SC_NS);
        }
    }
}

Basically, when I run the program I see the memory associated to the process steadily growing up second after second.

SystemC has been configured with the following switches:

--enable-shared=no

--disable-async-updates

and compiled as static library.

The host OS is ubuntu 16.04 and G++ version is 5.4.0 20160609

The same code compiled on an ubuntu 10.04 with SystemC 2.2.0 does not show any memory problem.

 

Any idea on why this happens?

Thanks
