--- Comment #1 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Be sure to enable Valgrind annotations (configure with
--enable-valgrind-annotations), otherwise false positives on sparseset
functions are expected: sparse set algorithm accesses uninitialized memory by
design (an explanation is available at e.g. https://research.swtch.com/sparse
).
