--- Comment #2 from Mike Kaganski <mikekaganski at hotmail.com> ---
This is not related to the bug in the incorrect check - rather it's similar to
https://github.com/FirebirdSQL/firebird/issues/4376. The problem is that FB
uses a global locking mechanism with a name that is shared across all FB
instances running on a session; and using a separate trace storage (which for
LO is placed in LO's own temp directory) is unsupported by FB currently.

The problem is reproducible in one of the following ways:

1. Open FireBird's isql utility and connect to a local FDB; then open an ODB
with embedded FB in LibreOffice, and try to open its tables;

2. Open a LibreOffice instance with an embedded FB ODB, and open a table in it;
open another instance of LibreOffice (e.g., a dev build; or use another user
profile) with another embedded FB ODB, and try to open its tables.

(the latter was how it occurred to me - the other running LO process was hung
and invisible, and I needed to kill it).
