Problem Note 56563: Running a PROC SQL query against a database table might result in a Segmentation Violation
 |  |  |  |  |
When you run an SQL procedure query against a database table that is accessed via the META engine, you might receive a Segmentation Violation. This problem typically occurs after you apply the hot fix associated with SAS Note 52776: "A Read access violation occurs when you run a query against an SAP table in a SAS® double-byte character set (DBCS) encoding."
The following is an example of the query and the resulting error:
LIBNAME TESTLIB META LIBRARY="Oracle Test Library";
PROC SQL;
CREATE TABLE WORK.RESULT_TABLE AS
SELECT DISTINCT NAME, AGE, PUT(AGE, DOLLAR.) AS AGEX
FROM TESTLIB.CLASS
ORDER BY NAME;ERROR: An exception has been encountered.
Please contact technical support and provide them with the following
traceback information:
The SAS task name is [SQL ]

/lib/amd64/libc.so.1:0xdcaf0The Segmentation Violation occurs when the size of the SQL DICTIONARY table that is allocated for the META engine is miscalculated.
As a circumvention, assign the library using the native LIBNAME engine rather than the META engine.
