I am trying to query relativity via the 64-bit relclient64.so that is included with the dataserver_2.1 installation.

Whenever I try to query a decimal value, the program segfaults.

the very simple test program runs the query  (I am using convert here to force the decimal value -- but when I query an actual decimal value out it has the same result).

I have installed and tested this on both redhat 5 and redhat 7, getting the same results.  Changing the query to CONVERT(10.0, SQL_DOUBLE) ends up working with no issues, as well as CONVERT(10.0, SQL_INTEGER)

The Query...
SELECT CONVERT(10.0, SQL_DECIMAL) test_val FROM <test_database>

The connection string....
Driver=relativity;ServerDSN=staging;ServerName=<servername>.1583;UID=<username>;PWD=<password>

odbcinst.ini

[relativity]
Description=Relativity Data Client
Driver=/opt/relativity/lib/relclient64.so
Setup=/opt/relativity/lib/relclnsu64.so

the GDB backtrace...
