On amd64, only test 20 abort traps.
So I built libspiro with AddressSanitizer on Linux and found out that there is a stack-based buffer overflow in spiro_to_bpath0(), causing the issues in tests 14 through 19 you've been seeing on sparc64. I could not reproduce the issue with test 20 on Linux, so I will need to make further investigations. For now I reported the issue [1] with spiro_to_bpath0(). Let's put this port on hold for now until upstream fixes this. [1]: https://github.com/fontforge/libspiro/issues/21
