PyTorch crashes when running with OpenACC
Labels: module: crash, triaged, module: openmp, module: third_party

### 🐛 Describe the bug

I'm binding OpenACC code with ctypes, and it is working fine. However, just by importing torch pkg, it crashes the application.

module_c.cpp
```
#include "module_c.h"

int addvector_cab(void)
{
    
    int i;
    float a[50];
    float b[50];
    float c[50];
    int n=50;

    for( i=0; i<n; i++)
    {
        a[i] = 1;
        b[i] = 1;
        c[i] = 0;
    }
    
    printf("ENTERED C FUNCTION!\n");

    if( n == 0 ){
        printf("DUMMY ERROR!\n");
        printf("EXITING C FUNCTION!\n");
        return(1);
    }
    
    #pragma acc parallel loop present_or_copyin(a,b) present_or_copyout(c)
    for(i = 0; i < n; i++){
        c[i] = a[i] + b[i];
    }

    printf("EXITING C FUNCTION!\n");
    return(0);
}

 ```


module_c.h :
```
#pragma once

#ifndef __MODULE_C_H_INCLUDED__
#define __MODULE_C_H_INCLUDED__

#include <iostream>
#include <string>
#include "openacc.h"
#include "stdlib.h"


extern "C" {

    int addvector_cab(void);
}

#endif

 ```

Compiling lines:
 ```
nvc++ -c -std=c++11 -acc -ta=multicore -fPIC -o module_c.o  module_c.cpp
nvc++ -shared -Minfo=acc -std=c++11 -mp -acc:gpu -gpu=pinned   -o mylib.so  module_c.o

 ```

bind.py : 

 ```
import ctypes
#import torch

so_file = "./mylib.so"

my_functions = ctypes.CDLL(so_file)

my_functions.addvector_cab.restype = ctypes.c_int

if( my_functions.addvector_cab() == 0):
     print("Returned OKAY!")
 ```

## Expected Outputs

One should expect:

```
ENTERED C FUNCTION!
EXITING C FUNCTION!
Returned OKAY!
```


However, importing PyTorch in bind.py (uncommeting line 2, nothing else changed) and running again, it returns:

```
ENTERED C FUNCTION!

libgomp: TODO
```

Not sure if is related, but I tried a similar approach with libtorch in C++, and whenever I tried to run a code with OpenACC and libtorch, same thing happened... it just crashed and output 'libgomp: TODO'. 

What I'm trying behind all this is to allocate a tensor via torch, share it with Cupy via Cuda_Array_Interface, and them use it in OpenACC (I'm already doing this last part without errors, if I allocated memory via Cupy). But the error I'm getting is way more basic than that... just by import torch, it crashes.

Any help/hint/axes are appreciated. =] 

EDIT: Due to space constraints, I've simplified some parts.... better documentation and example can be found here: https://github.com/estojoverde/Torch_OpenACC/blob/pytorch_openacc
