Thanks for that dnf suggestion. Here's the backtrace log with those rpms installed.

File Attachment:

File Name: backtrace.log
File Size: 4 KB


Incidentally, I'm using the following to create the logs:
gdb
> run
# program crashes
> set logging file backtrace.log
> set logging on
> thread apply all bt full
> set logging off
> quit
