    Segmentation fault with Oracle 32-bit DB client on RHEL 7.2


      sqlplus (from Oracle 32-bit DB client) is crashing on RHEL 7.  I have provided the GDB stacktrace below.

      Could you please advise what could possibly be wrong?

      Also, I am able to run sqlplus frpm 32-bit DB client and DB 64-bit installations perfectly fine on the same server without issues.


      # export ORACLE_HOME=/tools/oracle/
