Apparently, you have precision exception enabled for some reason. You can fix the problem by setting rounding mode to 8:
return _mm256_round_pd(a, 8);
I will do this in version 1.20 of vectorclass

The document you are referring to is wrong. You can find the complete description of rounding modes in "Intel® 64 and IA-32 Architectures Software Developer’s Manual" under ROUNDPD or in https://msdn.microsoft.com/en-us/library/bb514047%28v=vs.120%29.aspx
