Engine crashes with repetitive loading and unloading UDF [CORE5561] #5828
Submitted by: Alexander Muylaert-Gelein (gonline)
Engine crashes when you frequently load and unload UDF dll in firebird. Especially when you're accessing multiple databases.
1. Copy the fast.dll to the udf folder.
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.
