Thanks for merging the obvious fix. I was on vacation for the last two
weeks, and just got back. I sent another patch that restructures the
debug and non-debug code right before I went on vacation. Didn't get a
chance to look at the responses (if any). Will get working on following
up and re-working and re-sending the patch as needed this week.
