Hi,

It seems that I encountered some strange things while compiling with Visual Studio in 32bits : https://ci.appveyor.com/project/mbrucher/audiotk/build/job/ri2udu51pee9q67b

I managed to debug this with VS 2015 (VS2017 is OK, strangely), and it seems that there is a call to ATKDelay.dll!Eigen::internal::pstore<float,__m128>(float * to, const __m128 & from) Line 358 C++

but "to" is not 165 bits aligned, contrary to what it is supposed to be.

Are there known bugs with VS 2015/32bits?

Regards,

Matthieu
