The only way is to step through uw_frame_state_for() in libgcc and figure out what's wrong
with the unwind information. Probably with a simultaneous debugging of setup_rt_frame()
in qemu in order to compare addresses.
I thought I had enough _Static_asserts added so that any mistakes would be caught at
compile time, but obviously not. I'll have a look.
