Quick answer: Crash reports without symbols are stack-frame guessing games. A breakpad-style setup with a symbol server and CI upload turns 'somewhere in libgame.so' into precise file:line locations.
Without symbols, a C++ crash report is a hex dump. With them, it's a stack trace you can read at breakfast.
Generate dump_syms in CI
dump_syms libgame.so > libgame.so.symRun on every build. Store the .sym file in a symbol server keyed by build hash.
Strip the shipped binary
The shipped .so/.exe is stripped. Symbol resolution happens server-side at crash report time, not in the player's binary.
Wire the SDK
Bugnet SDK accepts minidumps. Upload .sym files alongside; crash reports automatically symbolicate at ingest.
Test the full path
Crash a known build intentionally. Verify the report shows file/line. If you see hex, the path isn't wired end-to-end.
“Symbol management is its own discipline. The setup is one afternoon; the return is months.”
Tag every build with a GUID. Symbol uploads, crash dumps, and source archives all key off the same ID. Lookups stop being detective work.
