Using the develop branch, I create a database create a few tables, insert a few rows and close the database using connection->close().
When I re-open the database, data is missing.
I don't use transactions and only use connection->close to close the database without any cursor->close or session-close.
I tried using log=(enabled=true,recover=on) but it doesn't seem to fix the problem.
I recognize that this a vague description of what happens, don't hesitate to ask for more information.
FWIW, I pushed the code online and you can reproduce the bug as follow:
This requires Guile 2.0.11
The second times guile -L . index.scm is run, the domain is said to be indexed but when the search is done no results is returned where the same thing returned results the first time.
