Querying ctxsys.ctx_version, gathering schema statistics, gathering statistics using DBMS_STATS for a table, or dropping a Text index terminates the session and logs an error in the alert.log:

ORA-7445: exception encountered: core dump [drumcmf()+184] [SIGSEGV] [Address not mapped to object] [0x000000000] [] []

The stack trace shows:

ssexhd <- sigacthandler <- drumcmf <- drurnew <- draccbi
<- drexumcx <- drexostatscoll <- spefcpfa <- spefmccallstd
