Subject: [postgresql-interfaces/psqlodbc] issue #132: Crash seen when attempting to use SetPos when looping through more than 20480 rows
Date: Mon, 14 Jul 2025 19:28:36 +0000
Message-ID: <[email protected]> (raw)

When looping through the rows in a table with more than 20480 rows using SetPos delete, the driver crashes with a segmentation fault (core dump). I have attached to this issue in a zip file:

- odbcquery_setpos_del_lax: ODBC app that can be used to recreate the issue
- odbcquery_setpos_del_lax.c: c file use to make the ODBC app.
- odbcquery_setpos_del.mak: Makefile to build ODBC app. Note that the directory paths to the install directory have been redacted.
- odbc.ini: ODBC ini file. Note the paths and sensitive information has been redacted.

If anything else is needed please let me know.
