which was exactly the question -- the same exact source code,
compiled with the same compiler flags (and i think even the
same compiler), produces the two different results.
My suspect was that somehow some of the compiler's header files
on FreeBSD explicitly initializes (to 0) some member of some class
thus resulting in having them in the .data section instead of .bss
