Hi all,
http://www.gnu.org/s/libc/manual/html_node/Aligned-Memory-Blocks.html
I was quite surprised to come across this. I never knew this was the
case. I wrote a quick, dirty, non-comprehensive, non-exhaustive test
and all of the malloc'ed pointers were 16 byte aligned.
May be it's worth trying to run the eigen's test suite on linux x86-64
assuming that the malloc is 16 byte aligned?
Your thoughts?
