BTW, you are likely using -D_FORTIFY_SOURCE=2 and that, unlike
-D_FORTIFY_SOURCE=1 has some extra restrictions beyond the C standard.
One is that the str*/stp* functions must not cross field boundary in
structures.
mem* functions don't have this restriction and can flow through from one field
into another, of course can't cross object boundaries though.
