Yeah.... I'm am pretty sure it is specific to TARGET=elf-x86_64 (i.e. no OS
specified). When I ran the same test on Ubuntu's native GCC it ran fine.
objdump showed pretty different assembly for the Ubuntu case, vs. the
cross-compiled case. For the code that does not crash (using the reference
instead of the pointer) the code is identical.
