There is no any 'large bodies of code', because all is dead simple. :)

For most ffi calls, a basic thing you need is to retrieve a function
pointer, like:

NativeBoost loadSymbol: 'gzopen' fromModule: 'libz'

and it doesn't works,
crashing with “EXC_BAD_ACCESS”  exception
somewhere in
misaligned_stack_error_

which gives a clue, why i got issues with pow() function before..
mac libs seems don't like misaligned stacks.. so i need to figure out
how to fix that
and align stack pages between the calls properly.
Strange that i met that only on Mac platform, and not before.
Maybe it because mac libs code extensively using MMX registers, which require
to use a properly aligned pointers when you loading the values in them.
