The "info.index" variable can be 31 in "1 << info.index". This might trigger an undefined behavior since 1 is signed.
Fix this by casting 1 to 1u just to be sure "1u << 31" is defined.

Thanks for the patch.
Unfortunately it seems that your MUA modified in quoted-printable and inapplicable with git-am as is. Since the changes are so small, I manually applied it now.
I see, thank you very much for pointing out this problem, I'll never use my MUA to send patch again. Also thank you for this manual modification.
Please fix the setup of your MUA at the next time, or better to try git-send-email to submit directly.
Sorry that I cannot configure my university email to work on git-send-email, I'll use my gmail to send patch via git next time.
That should work. In the worst case, use an attachment.
thanks,
Takashi
