More info, this error does not occur with DBD::Oracle 1.76.
DBD::Oracle 1.80 => works with 18c client, but fails with 19c.
DBD::Oracle 1.76 => works with all client versions.

I tested the same process on a server still using the 18c client and
the core dump does not happen. Our DBA is creating
ticket with Oracle, but I wanted to see if anyone else has had the
same issue.
Thanks,

I assuming this is the change causing the segfault with 19c client.
