Hey All -

We are having an problem with FB embedded hanging when process
terminates abnormally:

An access violation is thrown, causing the application to terminate.
All threads except the main thread seem to be killed, and the main
thread begins detaching dlls.

On DETACH_PROCESS call to DllMain, firebird shuts down all databases.
Part of this is a call to CCH_fini to shutdown the buffer cache
manager for the database.
Part of CCH_fini�s logic is to wait for the cache_writer to shut
down. To do this it waits on the ISC event dbb-

>dbb_writer_event_fini (cch.cpp:1239)

This event is set by the cache writer buffer thread when the thread
shuts down (cch.cpp:4381).

In our case however, the buffer writer thread has been killed without
setting the event, so the main thread blocks indefinitely.

Any suggestions on what we can do?

TIA
