while import full dump from AIX machine to X86 faced this error:

ORA-00600: internal error code, arguments: [smboPut:fixedlen2], [2], [7], [0], [66436], [], [], [], [], [], [], []
Failing sql is:
CREATE INDEX SHIPMENT_INS_DATE ON SHIPMENT ("INSERT_DATE") 
ORA-39083: Object type INDEX failed to create with error:
ORA-00600: internal error code, arguments: [smboPut:fixedlen2], [2], [7], [0], [66436], [], [], [], [], [], [], []

helped to set this parameter:

ALTER system SET "_newsort_enabled" = FALSE;

ps: version is 11.2.0.4.5
