Sorry if I wasn't clear. I'm using Firebird Classic Server on Linux, and 
the library is named libfbembed.so (as you know). I'm *not* using 
Firebird Embedded.

I knew that. Thanx.

Someone already did (Brad Pepers), and he sent code to firebird-devel, 
where Nikolay Samofatov agreed that problem lies in Firebird client 
library. The thread is named: "Firebird 1.5 segfault"

Here's what Nikolay wrote in his most recent post:

---- quote from firebird-devel -------
The strategic mistake was usage of STL objects in Firebird memory
pools (this forces us to re-define global delete). The fix is in
progress in FB2.0 tree (all needed classes are implemented and are
just pending to replace STL analogs).

I'll take a look at FB1.5 codebase and will recon what can be done
there with this problem. And yes, this is the real problem."
---- end of quote --------------------


After all this doesn't seem to be IBPP problem. There's one thing: some 
of the people said that it could be avoided if libfbembed.so was loaded 
before libstdc++.so. Is it possible to do something like that from IBPP?

Thanx for a quick reply.
