Comment # 2 on bug 1044807 from Adam Mizerski

I just accidentally reproduced with openarena:

1. Build SDLCL
1.a. git clone https://github.com/MrAlert/sdlcl.git
1.b. Edit Makefile and remove "-m32"
1.c. make
2. Create a wrapper script
export LD_LIBRARY_PATH="/path/to/sdlcl/${LD_LIBRARY_PATH:+:}${LD_LIBRARY_PATH}"
exec xterm -e gdb /usr/bin/openarena
3. Add the wrapper script to Steam and run it.
