ACN coding error 1004

While running one of the RTEMS_POSIX executables I described in the issue #16 (closed) I get an error while coding in ACN my types. It seems it is not always in the same variable because the type differs:

Could not encode RWcmdType (at C_ASN1_Types.c, 2008), errorCode was 1004

Could not encode TimeSynchroType (at C_ASN1_Types.c, 316), errorCode was 1004

It seems the problem is placed while coding an int32_t field, but I do not use that type in my definition.

Can you tell me what error is the error 1004?
