___lldb_unnamed_function in a symbolicated crash log

Question

I have a crash log produced on an iPhone OS 7.0.4. I have the appropriate .app and .dSYM files. When I symbolicate the crash log with Xcode 5, it shows me something like this:

Thread 0 Crashed:
0   MyProject          0x001df98a ___lldb_unnamed_function6108$$MyProject + 42
1   MyProject          0x001e0c49 ___lldb_unnamed_function6119$$MyProject + 9
2   MyProject          0x002928d5 ___lldb_unnamed_function8439$$MyProject + 13
3   MyProject          0x0027fa1f ___lldb_unnamed_function8072$$MyProject + 287
4   MyProject          0x0028e657 ___lldb_unnamed_function8368$$MyProject + 27
5   MyProject          0x002888d1 ___lldb_unnamed_function8257$$MyProject + 201

When I symbolicate the crash log with Xcode 4, it produces the right result - it shows me the classes and methods from my application where the crash has occurred. There are no anonymous blocks involved in the stack trace.

How come Xcode 4 and Xcode 5 produce different symbolicated crash logs? When I run the symbolicatecrash script in verbose mode, it shows identical results for both Xcode's: they match the correct .app and .dSYM files and both finish with these lines:

done.
1 binary images were found.

Answer 1

I had same problem and solved it by calculating address for ___lldb_unnamed_function from iOS crash reports: atos not working as expected post.

After that run:

xcrun atos -arch armv7(s) -o Xyz.app.dSYM/Contents/Resources/DWARF/xyz Calculated_Address
