Are you sure that this is an IBO problem? rtl120.bpl is the Delphi
2009's official Runtime Library. "Write of address 000000008" means
(most probably) that you're trying to write to a nil pointer. Perhaps
you have something like
MyIBOTable.FindField('FooField').AsString:='BarData'; and the 'FooField'
isn't present, hence FindField( ... ) returns a nil.

...but, of course, a dangling pointer can be present in IBO. The best
solution would be a small project which would show the problem to
discuss here and to add to 'Bugs' tracker on SF.net
(https://sourceforge.net/tracker/?atid=1126933&group_id=256127&func=browse)

+1. Sure - True RAD. And the things can be improved. We discussed with
the guys from Embarcadero and both we have 'some ideas' about how things
can be pushed forward. Also, we wait for Jason to stabilize the 'beast'
and after this to give also him some hints...

They're coming. A brand new state-of-the-art compiler is expected next
year (perhaps with a preview in 2009) which will support 64bit
compilation. Mind you, 64 bit executables are _slower_ than 32bit ones.
The main advantage of a 64bit binary is that it can address more than
4GB RAM. A little bit unlikely for a fat client. Yes, EMBT will provide
32bit _and_ 64bit compilers for Delphi/C++.

About cross-compiling: Yes, they are 'very actively researching' that
area ;-) - the compiler will have separate back-ends and front-ends,
thing which means that besides 32 & 64 bit support, it will be most
likely 'decorated' with Linux & MacOSX code-gens (and perhaps mobile).
Note that all the info above is not 'secret' and can be found in
different newsgroups, blogs, other sites etc.

About Firebird: I'll leave the honor to Helen to give more details. Just
to point out that Fb 2.5 will be a major step forward towards to 3.0.
Imho, 2.5 would be better renamed 3.0 and the actual 3.0 to became 4.0...

HTH,
