Are you sure you're using (at runtime) the libquadmath from the GCC 
version you're using (via -rpath / LD_LIBRARY_PATH, or linking with static 
rather than shared libquadmath), rather than an older shared library from 
your distribution?  This looks very much like bug 65757, which was fixed 
some time ago (for GCC 8 and backported to older release branches).
