It exits for the reported version (4.4.3) and as well as for trunk/4.6.
Abnikant, could you also post the patch that fixes this problem? Thanks.

This bug is invalid.
Your test code is in main() which returns an int. The return value is stored in
r24. So the code is correct to store the value in both r2 (test) and r24.
