| Subject: | Memory leak in db_verify() method. (libdb < 4.2) |
Hello!
I am using libdb 3.3.11 and Berkley DB 0.51.
I encountered memory leak problem when I have calling db_verify() method repeatedly.
I think, this problem causes libdb 4.1 or older versions.
libdb 4.1 or older versions are not destroying a DB handle in DB->verify() method.
