Do you still get this warning after PR #421?

[lemire]

I think that this has been fixed. If you still get a warning after running our most recent code, please open an issue.

[gvollant]

I have the warning with 5.2.8 which include PR #421
PR #421 modified simd8 but not simd16

[gvollant]

I created PR #425 with fixes

[lemire]

Great!
