I actually built everything first without any compiler optimizations, and 
rebuilt later with them.  It didn't seem to make any difference.

The second issue mysteriously went away on its own, which I find a bit 
troubling.  It may have been related to other changes that were happening 
on the machine at the time, but since I haven't been able to duplicate it, 
it's impossible to tell for sure what the culprit was.
