Dear Seth, We've compiled using DCMAKE_BUILD_TYPE=RelWithDebInfo but it doesn't look like I'm getting the additional debug info you're going to need. I'm going to try this again with -DCMAKE_BUILD_TYPE=Debug and see whether that helps matters. For completeness, here's the updated back trace. === GNU gdb (GDB) 8.2.1 Copyright (C) 2018 Free Software Foundation, Inc.
