Hi Stan FWIW I've written some notes on debugging GCC: https://gcc-newbies-guide.readthedocs.io/en/latest/debugging.html and in particular you might find the following useful: https://gcc-newbies-guide.readthedocs.io/en/latest/debugging.html#how-do-i-find-where-a-particular-tree-was-created Hope this is helpful Dave
