I'm on Ubuntu 14.04 and working on Fluorohydride/ygopro · GitHub but whenever I debug it using gdb whole computer freezes after 4 to 18 step overs. Nothing works except mouse cursor. I found the same the same behaviour in Arch linux also. But when I use open source drive everything works fine.
gdb ./ygopro b single_mode.cpp:108 run n ... ... ...computer freezes here
FYI: There is a consumer-oriented Catalyst forum, and you may want to search there to see if there is any help or information. If it's a replicatable defect, you can report issues as well.
But truly, I think you're in the right place here. I hope someone has clues for you. Let's see if anyone can chime in and perhaps add some light.
See the forum FAQ at: Where do I report a Catalyst issue?
