UE4Editor crash under Linux: Memory Problem?

Hello, today I’ve compiled 4.8 version of UE without any errors. (I’m on Ubuntu 14.04.1 Gnome 64 bit)
When I try to run UE4Editor it crashes, it returns me this error in the diagnostics.txt file: "Exception was “SIGSEGV: invalid attempt to access memory at address 0x00000003”;

How can I solve this problem?

EDIT: I’ve installed Bumblebee daemon, and I forget to type “primusrun” before ./UE4Editor. Whit primusrun I’m able to see the rectangular loading screen but when it finish to load, returns me the same error “Exception was…”;

This patch seems to solve my problem. For Ubuntu users: you have to create a file called “unreal48glibc.patch” and save it in “/etc/portage/patches/sys-libs/glibc” (if the folder does not exsist, create it);
