This could be a bug in gcc too. I had debugged a case in the aarch64 backend where it would change from the small coding model to the tiny one in some cases. I have a fix but I don't have it right now as I am on vacation. I can post it around Tuesday or so.  I saw this while using a gcc 4.7 based gcc and with a distro build (I cannot remember the program right now either, maybe python). 

Thanks,
Andrew
