I am not sure if it is the reason or not, but on the cc man page int
the BUGS section, there is a warning that
   "The optimizer may produce incorrect code if one asm() routine
    requires a jump to a label in another asm() routine. The optimizer
    should be turned off for these code segments."

You might also read the -j flag on the as man page for some further
explanation.
