Retrace / Mapping broken in 7.8.2 under some conditions

[davidgiga1993]

In proguard 7.8.2 the generated mapping contains a lot of strange entries causing the re-trace to generate huge stacktraces which do not represent the actual stacktrace of the app.

As my mapping file is ~20mb I'll only include the parts that are relavent to reproduce this issue:

Stacktrace

As you can already see in the mapping, the constructor mapping looks strange.

Retracing this stacktrace results in a large unexpected output:

I'm not exactly sure yet what causes this issue to appear, but as far as I can tell the only 2 changes were:

1. Updating the build JDK to 24 (compile target is still 1.8)
2. Updating proguard

This is just one example, this happens at a lot of different places in the mapping (also with regular methods)

[davidgiga1993]

Downgrading to JDK 21 doesn't solve the issue. Downgrading to proguard 7.5.0 does. So it's definitely something that broke between proguard 7.5.0 and 7.8.2

Thanks for the report, just to confirm:

• Can you share the steps to reproduce the problem on the linked project?
• Can you try 7.8.1?

[davidgiga1993]

Version	Result
7.8.0	Ok
7.8.1	Broken
7.8.2	Broken

As this lib is used in a larger codebase I need to create a new repo with a minimal reproducer first

[davidgiga1993]

Here is a reproducer:
https://github.com/davidgiga1993/proguard-reproducer

After running you can see in the strange entries in the mapping.txt file (for example just search for loadANGLE())

@piazzesiNiccolo-GS do you need any other information or did the repo help?

Yes thank you! We were able to reproduce and are investigating the root issue. Seems to be caused by #507 affecting the method/inlining/unique optimization, it doesn't happen when turning that off:
