Correction: it will print garbage on 32-bit platforms, where sizeof(int)
!=3D sizeof(intmax_t), but clang and gcc should still emit a warning.  You
don't need "a working arm setup" to see this; all you need is to
cross-build (make TARGET=3Darm TARGET_ARCH=3Darm buildworld).  It won't even
take long (15 minutes on my AMD FX8350) since the arm world is
significantly smaller than the i386 or amd64 world.
