I don't know enough about treeview controls to audit your code, sorry. 
But I suggest that you not focus on the red herring of native/cross, and
instead search for undefined behavior (e.g. accidently using a value
uninitialized.)  This sort of thing -- behavior that changes with
compiler versions or other environmental factors that should logically
have no effect -- is the classic trademark of unknowingly or accidently
invoking undefined behavior, which is quite easy to do in modern C.

Compile with -Wall and rectify all warnings, check the return value of
all function calls, and so on.  (The latter is good programming practice
anyway, so I would do it regardless of any debugging efforts.)
