We are running Solaris Intel with 11.2.0.2
This is a new oracle setup for us.
When running an insert from test table1 with 1 column(id), 2 rows(JT,TJ) into test table2 with 1 column(id) we get a core dump.

Further investigation shows that if we run a single row insert from select, it runs fine.

Could this be a buffer setting we need to adjust or ???
At this point, we are out of ideas to try.

What works
Insert into table2 (id) select id from table1 where rownum<2

What core dumps
Insert into table2 (id) select id from table1

We have narrowed it down via other test tables, etc... that it is not a permission issue and is only core dumping when multiple rows are being selected.
