Firebird crashes when UDF (Delphi?) gets loaded and unloaded frequently
-----------------------------------------------------------------------
Key: CORE-5562
URL: http://tracker.firebirdsql.org/browse/CORE-5562
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 3.0.2
Environment: win64 / fb3 64
Reporter: Alexander Muylaert-Gelein
Priority: Blocker
Attachments: all.zip
Engine crashes when you frequently load and unload UDF dll in firebird.
Especially when you're accessing multiple databases.
To reproduce
1. Copy the fast.dll to the udf folder.
2. copy multiple versions of the test.fdb to "d:\1\test.Fdb", "d:\2\test.fdb"
... "d:\10\test.fdb"
3. Launch firebird
4. Run the attached app. Or basically, Open a connection, execute the UDF
function, close the connection.
Do this with multiple threads on multiple databases. The firebird process will
crashes within 10 minutes with an access violation.
Workaround is to open another database that uses the udf. As long as the dll
stays in memory, no crashes. As soon as it is unloaded, you have a fair chance
that it crashes.
