The test fails because libstdc++ (probably the personality routine)
clobbers the d8 VFP register, which is callee-saved.
This bug goes away when I downgrade libstdc++ to the GCC 8 version, so I
filed a GCC bug:
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89093>
I don't plan to debug this further.
Thanks,
Florian
