Package: libdbi
Severity: grave
I try to create tables in the existing mysqldb test or in a nonexisting
sqlitedb. Later creates the db file on the fly.
With mysql I get SEGV on dbi_conn_get_table_list() function.
With sqlite the first table tbl_auth in first db file blogdb_auth is
created fine.
In a 2nd loop run a 2nd table tbl_user in a 2nd db file
blogdb_user should be created.
The db file blogdb_user is created with 0 size but then there is a SEGV
in dbi_conn_select_db() function at
open("/home/makolb/devel/blog/tests/db/build/./db/blogdb_user",
O_RDWR|O_CREAT|O_LARGEFILE, 0644) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
getpid() = 9161
