Sadly, this too is characteristic of the breed. I would say that
this confirms the "memory corruption" diagnosis. It also serves to
illustrate why it's so widely held that these are the hardest kinds
of problems to resolve in all of programming.
You mentioned this is a Cocoa app, so it's at least partly Objective-
C. If it's all Objective-C, then Garbage Collection (Objective-C
2.0) is specifically targeted to relieve you of a substantial
portion of the complications that lead to these problems. But that
requires you to be Leopard-only; any chance of that? And you have
to translate your program into the new idiom (there's a guide for
that, and mostly it consists of removing all retain/release/
autorelease calls, but there's a bit more to it than that). If your
app also has a lot of C or C++ memory management, the GC won't help
those parts.
Im getting this "deadbeef" syndrome often for even new Cocoa apps that
have nothing in them, just a blank window and a couple of methods, no
awakeFromNib or init overrides, so Xcode is deadbeefing on its own
standard initialization code not mine. Rebooting has no effect. I can
launch such apps directly from the Finder but from within Xcode Im
getting alot of deadbeefing. Do I need to reinstall Xcode 3.0?
