--- Comment #14 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- I wonder if this is just support that hasn't been updated in the GCC copy of libsanitizer. I recall fixing this bug (or one very similar to it) on the Clang side in 2015. There is some Power-specific logic in there for doing the stack unwinding. I will try to dig that information up and compare the two.
