I found some more, and the lines, which are triggering the debugger break:

if FGDS_Handle >= 32 then
FreeLibrary( FGDS_Handle ); <<--- here it is!

so it's somehow gds32.dll related or while it's loading/unloading.

I've verified the version of gds32.dll (renamed fbclient.dll) loaded by my
application and Delphi with ProcExplorer and it's 1.5.2.4731.
I updated the dll to the latest from Firebird 1.5.3.4876 and the error still
persists during the dll unload.

I tried to open, compile and run some of the IBO sample applications and
the error is not showing up on that programs.

Strange ...
