The --update option is meant to be used to rebuild the accelerator tables in an existing .dSYM. Can you share the crash log for when dsymutil fails?

When it "updates", does that mean it needs an existing dSYM file to begin with? And what are the actual pros and cons of using this flag? FYI I'm trying to generate a dSYM for crash symbolication for an iOS app.
