We tried to create a self contained program to reproduce the issue but
the issue is not observed with self contained program. It is only observed
with actual application code. So is why I am not fully confident of issue
being in psql odbc driver code but at the same time we do not find any
suspicion in using any of the ODBC APIs.

We will run the test again with debug enabled psql odbc driver code and
share the backtrace.

It is multi-threaded application.

ODBC configuration is almost all default:
# cat odbc.ini
[PostgreSQL]
Description    = data source for PostgreSQL
Driver         = PostgreSQL

# cat odbcinst.ini
[PostgreSQL]
Description    = psql_odbc for PostgreSQL
Driver         = /opt/PostgresClient/lib/psqlodbcw.so
Setup          =
FileUsage      = 1
Threading      = 0

Could be, but it's impossible to track it down without more information.
For starters, if you could try with a debug-enabled build of the driver,
so that we could see line number information and local variables in the
backtrace, that would help.

If you can reduce the test to a small self-contained test case that
reproduces the crash, that would be best. Can you provide more details
on the application and how it uses the driver? Is it multi-threaded?
What ODBC functions does it call? What config options are you using?
