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"

Hi Luke,
