> No core file found under /opt/home/trafodion/thaiju/HQC/equal_char. But a
> hs_err_pid2708.log file was generated (included in attached, to_repro.tar).
> Problem does not reproduce if I explicitly turn off HQC.
> To reproduce:
> 1. download and untar attachment, to_repro.tar
> 1. in a sqlci session, obey setup_char.sql (from tar file)
> 2. in a new sqlci session, obey equal_char.sql (from tar file)
