No symbolication for crash files with Xcode 7.3.1

Question

I am not getting a symbolicated crash file using Xcode 7.3.1. My current version of the app never has symbols, however an older version of the app seems OK and the crash file is symbolicated.

I have tried to manually re-symbolicate by dragging it onto a device as described in this SO answer.

I tried to manually use the symbolicatecrash utility as described by this SO Answer.

I have confirmed that the dSYM file exists in the archive and am using it in both of the above manual attempts to rebuild the symbols. Any idea what I have missed?

Did you upload in BitCode? If so, you have to "Download dSYMs..." in the Archives tab. — David K. Hess, Oct 12 '16 at 00:10
No, we investigated that option but it wasn't it. The "Download dSYMs" button isn't even active. For the record, our more recent versions of the app seem to be now working so we never solved why it didn't work for this one, or why it couldn't be manually symbolicated. However, the manual version is now working so I guess I just abandon this old problem as a mystery for the archives. — Jim Leask, Oct 12 '16 at 13:45

Some of the crash files we received from our customers are corrupt. Using Apple's instructions Getting Crash Logs Directly From a Device Without Xcode, the customer copied the crash log and pasted it into email.

Something along the way corrupted the crash file though, injecting \n characters in somewhat random spots. We manually fixed the corrupted crash file by comparing it to an example from our system and symbolication worked.

Note the incorrect new line characters in the corrupted examples below:
