Say I want to run a function and avoid it from memory leak, which may happen because the function actually result in memory leak, or because I need to kill it.

I currently use a new process on linux to separate two address spaces, and it works fine:

#include <sys/mman.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/wait.h>
#include <stdio.h>
#include <stdlib.h>

template<class F>
int execute(F& f) {
    int* shm = (int*)mmap(0, 64, PROT_READ | PROT_WRITE, 
        MAP_SHARED | MAP_ANONYMOUS, -1, 0);
    pid_t pid = fork();
    if (shm == 0 || pid < 0) {
        munmap(shm, 64);
        throw "Error executing";
    }
    if (pid == 0) {
        *shm = f();
        exit(0);
    }
    int status;
    waitpid(pid, &status, 0);
    int ret = *shm;
    munmap(shm, 64);
    return ret;
}

int testfunc() {
    // Memory leak
    for (int i=0; i<1048576; ++i) (new int[1024])[28] = 77;
    return 42;
}

int main() {
while(1)
    printf ("%dn", execute(testfunc));
}

• How to do this on windows?
• Is there better or worth-compare solution on linux?
