Couldn't continue because of atos error.

The dSym is good, the crash too, but still getting

Couldn't continue because of atos error. [link redacted]

Hi, thank you for the report. I will take a look at it.

(btw, I redacted the link from your post to remove the dsym link [should be kept secret!])

not sure about the error, but maybe a display of the error encountered would help :)

I ran into this issue. The problem is in the "Code Type" line. This is taken from a crash report that was very recently generated:

Code Type:             X86-64 (Native)

MacSymbolicator isn’t expecting the "(Native)" string. You can see this if you download the program, build it in Xcode, and symbolicate from there:

sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `xcrun atos -o "<path>/Contents/Resources/DWARF/<app>" -arch X86-64 (Native) -l 0x10fac4000 0x00000001101c2d25 0x00000001101bcf1e 0x00000001101bbb08 0x000000011016acf8 0x00000001101ba4f0 0x00000001101b0baf 0x00000001101b01f1 0x00000001101a8f74 0x000000011002ed8a 0x000000010fda03a3'

You can see the parameter to -arch is X86-64 (Native) instead of X86-64. Remove the "(Native)" from your crash report and it will run.

I'd submit a patch to check for this and parse it properly, but don't know Ruby.

@demitri I submitted a pull request based on your findings :)

@sweetppro Fantastic - thanks! Does this fix support both the "original" format and the "new" one with the extra text? Presumably this will be seen from different versions of macOS.

Fixing the code type parsing should prevent the atos error from appearing. Thank you for noticing that.

However, some crash reports will still have zero new information when symbolicated. In OP's case, the crash report he shared (redacted for privacy) might indicate a problem loading the app binary. Here's a snippet:

Notice that instead of showing the app name in the call stack, it only showed ???. The load address of the app binary is 0xffffffffffffffff

Binary Images:
                 0 - 0xffffffffffffffff +com.someapp.appname (1.4.0 - 58) 

If anyone has an idea of what might be causing this, that would be a huge help.

Sound like the same issue, I had. Fixed that for me.
