--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
At least with -O0 built cc1 without valgrind checking, can't reproduce this,
there are just the expected sparseset errors and nothing else.
I don't see how VALGRIND_DISCARD could be optimized away, it is a volatile asm.
Trying the configure you mentioned now (though on Haswell-E).
