The Russian Misson Control Center uses Firebird.

I quote Alex Peshkoff on the Firebird Development list

FYI – our colleagues from the Mission Control Center tested format of

VMT in the following environment

Intel(R) Itanium(R) Processor 9310

HP-UX B.11.31

HP C/aC++ Version A.06.26

and it differs from what we have on windows/linux. I do not have access

to that box myself, so I can’t report what is actually that format. But

an attempt to access it as we do on windows/linux cause an error.
