Firebird 2 is 'beta' at this stage.

1. Can you please produce a simple script to create a table, commit,
then insert such a record so that the server crashes.

2. Report this issue to the devel list (see the FB2 release notes
starting p1 for bug reporting procedures)

3. Firebird 1.5.3 is the latest stable build. Could you find time to
run your test case against this engine, and if applicable report the
bug in the bug tracker.

Well your statement should fail because of the implementation limit as
discussed in Helen's post, but the database engine should definately
not crash.

Possibly check with the FlameRobin project if there is a way to insert
longer strings through FR.
