Originally reported on Google Code with ID 472

In cio.c source of openjp2. I have found a bug when encode jp2 in Big-endian platform

Function:
void opj_write_bytes_BE (OPJ_BYTE * p_buffer, OPJ_UINT32 p_value, OPJ_UINT32 p_nb_bytes)

Bug code line:
const OPJ_BYTE * l_data_ptr = ((const OPJ_BYTE *) &p_value) + p_nb_bytes;

Fixed: 
const OPJ_BYTE * l_data_ptr = ((const OPJ_BYTE *) &p_value) + sizeof(OPJ_UINT32) -
p_nb_bytes;
