Just for future reference if anyone goes digging, this also fixes the use case
of -D_FORTIFY_SOURCE=2 and printf inside

Right for aarch64, most people won't use +simd/+nosimd combo (though it might
show up inside the kernel) but they might use +sve/+nosve ...
So the aarch64 bug should be fixed ...

The problem is an ordering problem.
Namely:

Not to mention, for calloc like the above where size is non-constant, it
wouldn't know how many there are (it would need some magic for all).
Anyway, even constant number of 0s at the end of string > 1
