A volatile asm is not a full barrier.
Please read http://gcc.gnu.org/onlinedocs/gcc-4.3.2/gcc/Extended-Asm.html.
" Note that even a volatile asm instruction can be moved relative to other
code, including across jump instructions. For example, on many targets there is
a system register which can be set to control the rounding mode of floating
point operations. "
This came about with the fix for PR 17884.
