This problem can occur on any platform.
Symptoms
When trying to create a unique index on a table having a DATE column, the following error is raised in the SQL*Plus session:
ORA-03113: end-of-file on communication channel
and on the server, an error similar to the following error is seen in the alert.log:
ORA-07445: exception encountered: core dump [smboQbNxt()+96] [SIGSEGV] [Address not mapped to object] [0x303104000C000A00] [] []
The trace file for the ORA-7445 shows a call stack:
... smboQbNxt ksxb1buf rworofprFastUnpackRow qersoFetch ...
After applying the patch for bug:4655998, an error like the following error is returned instead:
ORA-600 [smboFld2Kb:fixedlen2], [6], [7], [2], [50]
The 4th argument (2) will identify a column being of type DATE (column number starts with zero, so 2 would refer to the third column in the table).
