Methods Overlap for Kotlin Code

[embydextrous]

We are seeing method line numbers overlapping for Kotlin files (see bold part below).
Due to this the deobfuscation doesn't work well and get multiple deobfuscated stackframes for a single obfuscated stackframe causing confusion while debugging.

For ex: for line 214 we get onStart, update and get methods in the deobfuscated trace.

Is this a known issue or compatibility issues between proguard and kotlin version? We are using Kotlin 1.9 and Proguard 7.0.0 , gradle 7.2.

For Kotlin files

(com.google.gson.Gson,com.example.simplestore.presidio.RxSimpleStore,com.example.common.base.Clock,com.example.app_lifecycle.core.AppLifecycleProvider,com.example.core.UComponentCoreParameters,com.example.analytics.core.PresidioAnalytics) ->
> 93:387:void onStart(com.example.rib.core.WorkerScopeProvider) -> a
136:138:void onStop() -> az_
144:388:void update(java.lang.String,com.example.core.data.UComponentHolder) -> a
196:236:io.reactivex.Observable get(java.lang.String) -> a

Hi @embydextrous ! Can you share a full sample that reproduces the isssue?

Hi @embydextrous ! Can you share a full sample that reproduces the isssue?

Do you need the mapping file and raw stacktrace?

deobfuscated.txt
obfuscated.txt
2d99cb10-4897-11ef-bcc6-0f1a076ae26d.txt.zip Mapping file (zipped due to large size)

From the obfuscated stacktrace:

at com.uber.car.map.core.overlay.e.a(SourceFile:133)

the above line results into multiple lines in deobfuscated stacktrace

at com.uber.car.map.core.overlay.CarMapOverlayWorker.onStart(CarMapOverlayWorker.java:133)
at com.uber.car.map.core.overlay.CarMapOverlayWorker.subscribeToMapChangesWithVisiblePaddingChangeAPI(CarMapOverlayWorker.java:133)
at com.uber.car.map.core.overlay.CarMapOverlayWorker.onStop(CarMapOverlayWorker.java:133)

in the mapping.txt line no. 133 corresponds to all these 3 methods.
