You could be getting either of the following errors in the alert.log or all of them while running an update statement:
ORA-07445: exception encountered: core dump [_memmove()+2369] [SIGSEGV] [Address not mapped to object] [0x9FFFFFFFBF200000] [] []
ORA-07445: exception encountered: core dump [kgidum()+1536] [SIGSEGV] [Address not mapped to object] [0x9FFFFFFFBF200000] [] []

The call stack extracted from the trace file for the above error(s) will look similar to:
... updgrh upduaw kdusru kauupd updrow qerupRowProcedure qerupFetch updaul updThreePhaseExe updexe opiexe kpoal8 opiodr ttcpip opitsk opiino opiodr opidrv ...
In cases, the call stack functions may be presented like:
... intel_fast_memcpy updgrh PGOSF480_upduaw kdusru kauupd updrow PGOSF536_qerupRow Procedure qerupFetch updaul updThreePhaseExe updexe opiexe ...
If you enable the 1551 event tracing, a trace file is generated at the time of the internal error reporting the following:
Errors in file /u10/app/oracle/admin/sid/udump/sid_ora_x.trc:
ORA-01551: extended rollback segment, pinned blocks released
ORA-01551: extended rollback segment, pinned blocks released
