Comment 4 for bug 1699058

   "Am I right in understanding from your description above that if you don't build the libs with -flto, gdb correctly shows the paths?"

   "Also, will you be able to share with us a narrowed down set of sources so that we can use to reproduce the issue you're seeing on our side?"

Okay, I'll try and come up with something over the next few days.
