PIN app terminated abnormally due to signal 11

[Parveen Duhan]

Hi All,

Getting this error "PIN app terminated abnormally due to signal 11" while running a multithreaded program(using pthreads).

• I m compiling the program statically
• No issues while running single threaded application
• Programming running correctly on base machine.
• Ubuntu 22.04.1 LTS
  
• PIN 3.21
• Tejas 1.4

Source code:

#include <iostream>
#include <pthread.h>
 
// size of array
#define MAX 1024
#define MAX_THREAD 2
 
using namespace std;
 
int a[MAX];
int sum[MAX_THREAD] = { 0 };
int part = 0;

void setArray()
{
    for(int i=0;i<MAX;i++)
    {
        a[i]=i;
    }
}
void* sum_array(void* arg)
{
    int thread_part = part++;
    for (int i = thread_part * (MAX / 2); i < (thread_part + 1) * (MAX / 2); i++)
        sum[thread_part] += a[i];
       
   return NULL;
}
 
int main()
{
    setArray();  
    pthread_t threads[MAX_THREAD];
    for (int i = 0; i < MAX_THREAD; i++)
        pthread_create(&threads[i], NULL, sum_array, (void*)NULL);

    for (int i = 0; i < MAX_THREAD; i++)
        pthread_join(threads[i], NULL);

    int total_sum = 0;
    for (int i = 0; i < MAX_THREAD; i++)
        total_sum += sum[i];

    cout << "sum is " << total_sum << endl;
    return 0;
}
