Hi!
Thanks for all your suggestions.
I tried out everything to find out what most of you already suggested.
it had nothing to do with the compiler settings.
It actually was a legacy releaseExclusiveAccess after the DRErase
that for some reason
crashed the program in 10.3 but not in 10.4.
The other issues where all seperate bugs invisible in 10.4.
The main trouble for me was testing it without having to convert
the project back to a XCode1 (the only one that would run in panther).
Which was of course very inconvienient.
If such bugs are not reproducable on the development machine
is there any other easy way to debug it for an older system?
thanks and kind regards
Thomsa

Sounds like you have a memory corruption problem. DR is

Well, using a DRErase is not very much magic,
and why would that only affect 10.3 and never occur in 10.4?
Plus, this is not the only issue. There are also others like the
carbon code that does not work all of a sudden,
random crashes even leading to the Finder logging out the user etc.
Nothing of that sort in 10.4 on ppc nor intel.
It's in the nature of memory bugs that when you screw up some
memory it may behave in very nondeterministic ways, because on
every installation memory is laid out differently.
If you're interested in reading more about this, I've written some
articles on memory management on my web site, and I also touch this
subject as part of the C tutorial there.
