yes, i also think it's a alignment problem, because my configure script in orbit2

didnt work properly, i copy this section of orbit-config.h from orbit 0.5.12 's:

#define ORBIT_ALIGNOF_CORBA_OCTET        1
#define ORBIT_ALIGNOF_CORBA_BOOLEAN      1
#define ORBIT_ALIGNOF_CORBA_CHAR         1
#define ORBIT_ALIGNOF_CORBA_WCHAR        2
#define ORBIT_ALIGNOF_CORBA_SHORT        2
#define ORBIT_ALIGNOF_CORBA_LONG         4
#define ORBIT_ALIGNOF_CORBA_LONG_LONG    4
#define ORBIT_ALIGNOF_CORBA_FLOAT        4
#define ORBIT_ALIGNOF_CORBA_DOUBLE       4
#define ORBIT_ALIGNOF_CORBA_LONG_DOUBLE  4
#define ORBIT_ALIGNOF_CORBA_STRUCT       1
#define ORBIT_ALIGNOF_CORBA_POINTER      4

is it right?
