(In reply to Dmitry G. Dyachenko from comment #8)
valgrind' messages looks unrelated to ICE.
I rebuild r205461 with memset(set, {0,0x42}, n_bytes) instead of
VALGRIND_DISCARD (VALGRIND_MAKE_MEM_DEFINED (set, n_bytes))
in sparseset.c::sparseset_alloc() without luck.
But I see one strangeness: according to /proc/cpuinfo I have Intel(R) Core
i5/760. Gcc is build with arch/tune=native, but while running selects
tune/arch=i7.
