this solves the problem this number is too large for an int
static int LUACALL wxLua_wxStyledTextCtrl_SetMarginMask(lua_State *L)
{
double doubleMask = wxlua_getnumbertype(L, 3);
int mask = (doubleMask > INT_MAX) ? (int)((doubleMask - INT_MAX) -1 )|
INT_MIN : (int)doubleMask;
---------- you can look below if you like it shows some detail of
