Hi,
We encountered a crash that points to psql odbc driver. The crash is not at fixed at same point but it always points to psql-odbc driver. It is at same two places shown below. Kindly let me know if this is really an issue in psql code!
OS: Linux (windriver)
Psql odbc version: Latest 09.03.0300
Postgres server version: 9.1
Scenario: System restart (once after around 6 to 8 restarts)
Back trace:

Note: If we enable the logging the system becomes damn slow and in most cases we don’t even hit the crash.
