Hey chaps,

when running ./geekbench4 --compute, the tool exits to the command promt immediatley after switching from Running Gaussian Blur to Running Face Detection, it only stays at Running Face Detection for a split second. Here's the full command line output:

tiedemate@Surfbook:~/Dropbox/Soft/Geekbench-4.3.3-Linux$ ./geekbench4 --compute 
Geekbench 4.3.3 Tryout : http://www.geekbench.com/ 

Geekbench 4 is in tryout mode. 

Geekbench 4 requires an active Internet connection when in tryout mode, and  
automatically uploads test results to the Geekbench Browser. Other features  
are unavailable in tryout mode. 

Buy a Geekbench 4 license to enable offline use and remove the limitations of  
tryout mode. 

If you would like to purchase Geekbench you can do so online:

If you have already purchased Geekbench, enter your email address and license  
key from your email receipt with the following command line: 

 ./geekbench4 -r <email address> <license key>
