--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
It's possible e.g. your GCC has a miscompiled libgcc or other bug
affecting float128 code. I'd suggest adding instrumentation to the
relevant code in glibc to trace the values of variables through the
affected functions until you find the first point something differs (at
all, even by 1ulp) between working and broken glibc.
