Ok, since i've already looked like an uneducated fool today and i'm
grasping at straws...
Question: why do i get an unaligned array as soon as g++ (4.1.0
20050327, cygwin) finds out that it's static (i mean even if i try to
fool it around a bit)?
It seems to only happen with multidimensionnal arrays, or arrays large enough.
color_t is a __m128 in disguise.
color_t above; -> aligned
static color_t above; -> unaligned
I've tried countless alignement attribute variations and/or
indirections but with the same result.
Other statically allocated, but smaller, thingies in the same unit are
Have i crossed some magic treshold?
