After I updated my x86 Fedora 25 system to Fedora 26,  some Unit Tests
started failing. I fired up 32 bit Arch, and I'm getting the same
failure now. Any ideas  what change might be causing this or what I
should check? 

Below is the Fedora log:

Below is the Arch Log:

The 32bit LO-based Java programs crash (AKA Segmentation fault) with the current implementation of 
the StackClash fix for 32bit x86 (same happens, if you build LO 32bit in a i386 chroot on an amd64 
system - BTW). Updating my Jessie build box also broke my TB and my Jenkins LO builds. More info:

Quote from the Debian bug: "You should also be able to work around it by temporarily disabling the 
Stack Clash fix using the kernel parameter stack_guard_gap=1"
