Revised version of test program
Hi Andrew,
I revised the test program with the current version of those two functions. The
erroneous behavior w.r.t. optimization is unchanged.
>From what poking around I could do, the problem appears to occur in the binary
search in time2sub(), which is why making the lo/hi variables volatile appears
to straighten things out.
