No changes. It still raising an exception when calling
isc_detach_database.
The error message is: 'Access violation at address 10024758 in module
gds32.dll. Write of address 023CDA7E.

If I change back the gds32.dll to fbclient.dll, the error message will
be the same, but pointing to fbclient.

I see a similar error in [Firebird-devel] newsgroup with subject:
'gds32.dll thread-safety'.
I am not sure if there are any connection, but my program is also have
multi threaded database connection. Actually my program is not in the
multi threaded mode while it is disconnecting.

Best regards,

Sachli
