You can also try running  "dwarfdump --verify" on your dsymutil file  
(not on the dSYM bundle, but on the file inside the bundle). It  
sometimes gives a bit more information. Also simply using "dwarfdump - 
a" can be helpful to see wrong references (e.g., if the type info is  
structurally invalid then dwarfdump may simply stop dumping at that  
point, so you know where the error is).
