When running a query on a table having a functional index and using linguistic sorts (nls_sort='BINARY_CI' and nls_comp='LINGUISTIC'), it may core dump in evaopn2():
ORA-07445: exception encountered: core dump [evaopn2()+228] [SIGSEGV] [Address not mapped to object] [0x000000000]  
The call stack looks similar to:
... evaopn2 evareo evaior qertbFetchByRowID ...
The query has a functional inlist ie. a list of OR'ed conditions like:
SQL> select .... from ...
where (<condition1> OR <condition2> OR <condition3> OR ...)
