Moving from OSX 10.3 (XCode 1.5) to OSX 10.4 (XCode 2.1)

Hopefully someone can help!
1) XCode/OSX compatibility:
As far as I have understood OSX 10.4 runs only XCode 2.0 or later and
XCode 2.0 cannot be installed on OSX 10.3 and on the other side XCode
1.5 cannot be installed on OSX 10.4. This seems so restricted and
complicating that I hope to have missed something or it this really
the case? How are people dealing with this restriction, if they want
to develop for all (let's say starting with OSX 10.2) OSX versions?
2) Problems when using XCode 2.1 on OSX 10.4:
I have a large C++ application that runs fine on OSX 10.3 but reports
strange memory errors on 10.4!
The application is depending on several frameworks that have been
released for XCode 1.5 and has therefore been build in XCode 1.5
under OSX 10.3.
The same application has now been rebuild under XCode 2.1 using gcc
3.3 because the native gcc 4.1 would simply not run and seems to
compile and link just fine.
Only when now running the application very strange memory allocation
errors occur. When running in the debugger environment the debugger
reports a EXC_BAD_ACCESS error message shortly after starting the app
and when running without debugger the applications reports errors
like "LJSApplication(628) malloc: *** Deallocation of a pointer not
malloced: 0xb06fe20;".
I have been trying to track down this problem to the root by
debugging and tracing for quite a while but cannot find any error in
the app itself even when reducing it to a simple example app.
I have also found out, that also when running the application that
has been build with XCode 1.5 on OSX 10.3 from an OSX 10.4 system,
the application that runs just fine on OSX 10.3 reports the same
memory allocation errors on OSX 10.4. And now comes the best: Also
running the application build with XCode 2.1 under OSX 10.4 runs like
a charm when being started from an OSX 10.3 system.
I'm totally lost! Is this all because I would need a new set of new
libraries/frameworks etc. from all my 3rd party suppliers? Is
something wrong with the way how those 3rd party libraries are build?
Thank you in advance
-Dieter
