This works without warnings. Could you try to explain how this relates to the failed inlining in ei_redux_novec_unroller?

well, there:


the issue only occurs for even sizes which are the only one being vectorized, so I wanted to be sure VS was able to align a function calling SSE intrinsics..


I have to correct my observation from before. It does not seem to be SSE related since with test_triangular, there are still failed inlines. I attached the list of warnings of test_triangular.

Nonetheless, the warning did not appear with the example from above while SSE was disabled.

that's not a good new. What about this simple example:

#include <Eigen/Eigen>
using namespace Eigen;

template<typename T>
EIGEN_STRONG_INLINE void funca(T* a, T* b)

int main(){

if it compiles fine then we can try to add a few more indirections...

Ok, some more infos.

The issue is SSE specific, i.e. with 32bit builds and neither /arch:SSE nor /arch:SSE2 set, the warning disappears.

Furthermore, it does not only occure in Redux.h - compiling the unit tests in release with SSE reveals all occurences. Please remember that this issue is currently only proven to occur on VC9. I attached an incomplete list of reports generated by compiling parts of the unit tests.
