Also I think this is related to -ftrapv (trap on signed integer overflow) as disassembly shows ud1l (undefined instruction 1), recompiling with -fwrapv might make sense to add this flag into the buildsystem to avoid UB.

Had to remove -ftrapv, simply adding -fwrapv didn't work. Marking it as fixed as it's effectively a build configuration issue on my end.
