Hello All,

I have an Test.cpp which is run under sandbox(RHEL7):

Test.cpp content:

#include<stdio>

 int main(void) {

  int a = 1/0;

  return 0;

 }

compile it using gcc(4.8) Test.cpp which produces the a.out

Now running a.out prints floating pointing exception on console

Now i thought that if i redirect stderr to a file, i expect the error to be printed in file.

But that is not the case it still continue to print in console.

Googling reveal that under such exception the program is terminated immediately and if you capture the stderr of bash then it should redirect.

So i run

Bingo error get printed in err file.

Now the MAIN GAME STARTS

i want to run it under sandbox 

so i run:

But there is nothing printed in err file or in console.

How to capture stdout and stderr under such situation ?

Thanks

Bhuvan
