There was a long pause there, as I didn’t get to try out those debugging instructions from Frederik right away. They worked great Happy for any assistance whenever I can get it! Thanks!

Was able to get all of that output, though I wish I had a clue what any of it meant. Let me know if there’s other stuff that would be helpful.

I should probably note that I’m running this as: ./R -d gdb-ia from within $BUILDIR/bin. gdb-ia appears to be the Intel copy of gdb (they had their own debugger but eliminated it sometime back).
