Duplicates CORE3718

32 bits gds32.dll from 2.5.7
In case that connection to DB was successfully but auxiliary event connection failed to establish, other operations on same DB handle are blocked.

Call of isc_cancel_events not help.

If I use fbclient.dll from Firebird-3.0.3.32798-0_Win32, it is working fine.

Test is simple:
1. Configure FB server but on firewall open only 3050. Block all other ports.
2. On client side connect to DB (this will be successful)
3. Try to register events. but this will failed due to server firewall.
4. After that, you cannot do any operation with DB using handle obtained in step 2.
