This problem can occur on any platform.
The following error was generated when using Quest SQL Navigator software (SQLNav4.exe), which connected via SQL*NET and executed the SQL over a dblink. The Oracle client version was 817; the local and remote databases were both 10.2.0.3. The error did not reproduce when the query was run from sqlplus.
ORA-07445: exception encountered: core dump [ttcfour()+1052] [SIGSEGV] [Address not mapped to object] [0xFFFFFFFF7B492D28]
