Crash seen when attempting to use SetPos when looping through more than 20480 rows

[gabriellestein]

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.

May I ask what version of psqlodbc you are using ?

This was tested against version 16. I will build the must up-to-date release in the repo (17.00.0006) and retest.
*Edit: I was just able to recreate against 17.00.0006.
