I don't know whether it is a bug or not.

Consider the following example:

short int sh1 = 1;
short int sh2 = 2;

printf("Size of short: %d\n", sizeof(short));
printf("Size of int: %d\n", sizeof(int));
printf("Size of expr: %d\n", sizeof(sh1+sh2));

Output:
Size of short: 2
Size of int: 4
Size of expr: 4

GCC is converting short to int while doing any arithmatic operation. Can anyone
explain why it is happening and where exactly(function) does this conversion
happen?

This is the effect of the integer promotion rules.
