c++ - Passing value as reference -

i have function (method)

my struct created complex objects, in end acts like

struct mystruct{  string a, b, c, d, e, f; int g; string h, k, l, n, o, p, q; int r; } 

i did way because database library , uses inside types, more dbstring, dbint.

void checkdata(mystruct& st){  } 

in 32 bits when try access value works. in 64 bits after fourth element pointers "inside object in struct" points nothing

sorry, problem reference sent external library , define type different in external library.
