Bug#427386: Patch

[Vincent Le Ligeour]

Hi,

This bug is related to the lack of check of the screen pointer returned 
by SDL when creating screen buffer. This could be checked by the 
following patch :
http://ultrastar-ng.cvs.sourceforge.net/ultrastar-ng/UltraStar-ng/src/main.cpp?r1=1.38&r2=1.39
That clearly exit and print why it exits.

Thank you for reporting and pointing exactly where the bug was.

Vincent
