Getting a core dump from a simple C program

To fix this issue I'm trying to get the code working, and I don't know where's a mistake. I've tried with references etc but it does not work. , You should take a deeper look at your start() function definition.
code :
void start(int tab[],int n,void (*f)(int,int))
void start(int tab[],int n,void (*f)(int[],int))

This might help you i was trying to write a simple multithreaded program. It is dumping the core. I have my function that is called when a thread is created below: , This line is wrong:
code :
printf("Thread %d starting...\n",*tid);
printf("Thread %d starting...\n",(int) t);

Hope that helps I'm not surprised that produces a core dump. line 10 declared a pointer that points to nowhere -- there is no memory allocated to it. If x is supposed to be an array then use malloc() to allocate memory for the array x = malloc(10 * sizeof(int)); will allocate an array of 10 integers.
Why is this program not creating a core dump?

To fix the issue you can do According to this question and this one, the operating system is freeing wathever you've malloced in your program as long as you close it, moreover in a simple program like mine it's not so important. ,
Shouldn't both programs create a core dump?

I wish this helpful for you The program crashes, because the stack overflows. And this is because you call foo() recursively forever
code :
struct derived : public base {
    void foo() { base:foo(); }
};
base:
    foo();
   a.cpp: In member function 'virtual void derived::foo()':
    a.cpp:6:18: warning: label 'base' defined but not used [-Wunused-label]
         void foo() { base:foo(); }
              ^
    a.cpp: In function 'int main()':
    a.cpp:13:12: warning: deleting object of polymorphic class type 'base' which has non-virtual destructor might cause undefined behaviour         [-Wdelete-non-virtual-dtor]
         delete b;
                ^
