I just thought that it's also possible to use the following workaround:
abs_residual_partition_sums[partition] =
(FLAC__uint32)_mm_cvtsi128_si32(mm_sum);
+#if (defined _MSC_VER) && (_MSC_FULL_VER == 190023918) && (defined
FLAC__CPU_X86_64)
+ abs_residual_partition_sums[partition] &= 0xFFFFFFFF;
+#endif
probably this will be faster than to disable optimization.
