A change to one of the tests exposed that we dereference pointers in the session and connection handle without checking for validity.
It's tempting to either add a NULL check or a WT_ASSERT checking for a NULL session to the include/api.h API_CALL macros.
Adding the check didn't solve the particular test issue. The test (test_txn01) was doing:
self.session.begin_transaction()
cursor = self.session.open_cursor(self.uri, None)
cursor.reset()
session.commit_transaction()
cursor.reset()
The commit_transaction call frees the cursor structure (via __wt_cursor_close). The second cursor.reset call is operating on a freed pointer - thus the cursor.session field can't be accessed safely.
