I was compiling a simple floating-point benchmark program, and I
noticed that it gave me different results depending on whether or
not I had a printf statement in the code.  The odd thing is that the
printf statement was entirely out of the timing loop, so it shouldn't
have any effect at all on the performance measure spit out by the
program.  Nevertheless, it has an effect.  Has anyone ever seen something
like this?  I can supply the code if people would like, so they can
test it -- the program is about 100 lines long.
