I just transitioned my (primarily Cocoa based) code from building 32-bit i386/PPC, to also include x86_64. Unfortunately, when launching the 64-bit version I'm getting a crash at launch and I can't figure out how to debug it. Stack trace at the bottom of the email.
- The crash does *not* occur when the application (either release or debug build) is launched within Xcode. - The crash *does* occur if I launch the app with gdb from the command line (same stack trace). - I have confirmed that all the dependencies are built x86_64 by using 'file' to make sure the architecture is represented in all dependencies. - I have the same crash building everything with GCC 4.2 as well as LLVM 1.5. - The 32-bit version launches without any issues. - The debug build is x86_64 only, so I can confirm that Xcode isn't somehow launching a 32-bit version. Can anybody offer any tips on how to debug this crash?
