Earlier I had posted a question about why a straightforward use of
an open dialog would fail when debugging in Xcode 3.2 under Snow
Leopard.
On a hunch I purged the project WHICH I HAD INHERITED FROM XCODE
3.1.1 UNDER LEOPARD and recreated it from scratch under Xcode 3.2
under Snow Leopard using all the same files from the Leopard project
but not the project itself and, lo and behold, the open dialog
debugging problem disappeared and the built application executes as
it should.
If it's written anywhere that you must do this or if Xcode 3.2 has
an "inherit from an earlier version" option I didn't see it.
All this means is that there was some build setting in your previous
project that was causing Xcode to build your sources in a way that
caused a crash. This could represent a compiler bug, or (more likely)
a mismatch between the assumptions in your source code and the effects
of the build settings. For example, if your old project had settings
that conflicted with Snow Keopard's default compiler model (64-bit
Intel with gcc 4.2 for the Snow Leopard system headers), it might not
work without certain fixes, but the project template from Xcode 3.2
would have compatible settings from the start.
Looking at the compiler invocation build transcripts for each build
would tell you right off what's different.
