Sorry, I should have provided more info.

I have created a ticket:

http://sourceware.org/bugzilla/show_bug.cgi?id=12974

Cmd line:
arm-none-eabi-gcc -g start.S main.c  -o test.elf

^ Note the -g is necessary to see line numbers rather than assembler
hex refs in the outout. I expect you already knew this though!

I've attached a zip to the bug ticket 12974 with the start.S and command line.

Thank you for taking a look.
