Sorry if my sentence is confusing If I give a proper hexadecimal encoding % followed by 2 hexadigit (i.e. for e.g %2f, %2a) every thing is fine. When I pass a invalid hexadigit encoding eg: *%2h, %2m *among the host string e.g "postgres://*%2h*ome*%2m*ithun:5555/postgres". then "PQconnectdbParams()" fails before calling connectOptions2(). In that case failed PQconnectdbParams() also return a PGconn where connhost is not set. If we call PQpass(), PQReset() on such a PGconn we get a crash. A simple test case which crash is: ./psql 'postgres://%2hxxx:5555/postgres' Call stack: -------------- #0 0x00007ffff7bb8d4f in PQpass (conn=0x68aa10) at fe-connect.c:5582 #1 0x00007ffff7bb907a in PQconnectionNeedsPassword (conn=0x68aa10) at fe-connect.c:5727 #2 0x00000000004130aa in main (argc=2, argv=0x7fffffffdff8) at startup.c:250 -- Thanks and Regards Mithun C Y EnterpriseDB: http://www.enterprisedb.com
