Hello,

  I am using Oracle 8.0.5.0.0 under Solaris 2.6. I have created a small class which has the sole purpose of connecting to the data base. This class works fine, so I believe. I have created a small test bed with five tests:

1 - connect to the DB using default UID and PWD (works fine) 2 - connect to the DB using alternate UID and PWD passed in as aguments (works fine)
3 - connect to the DB using invalid UID/PWD (works fine handles the error correctly)
4 - connect to the DB using alternate UID and PWD passed in as aguments twice (works fine handles the error)
5 - connect to the DB using alternate UID and PWD passed in as aguments and try and disconnect twice (works fine handles the error)

Each test is a seperate subroutine called from a main program. When I execute tests 1 to 3, all works fine, when test 4 executes the program core dumps with SIG 11 (segmentation violation) I have traced it and the call stack is below:

   main()
   test4()
   DBConnection::DBConnection(this = 0x40100, uid = 0x39d88 "cissuser", pwd = 0x39d94 "ciss")

   realfree(0xb0cb8, 0x742b811c, 0xef6a9710, 0xef6a3100, 0xb0cb0, 0x7420746f)

It fails when I try to log in again. If I remove the third test from the main program tests 1, 2, 4, and 5 work correctly. Need to know why this occurs. Any help would be greatly appreicated...

Thanks in advance
