Latest passing run was https://github.com/graalvm/mandrel/actions/runs/4878221407/jobs/8703969691 (4 days ago).
The github image runner in both cases is Image: ubuntu-22.04 Version: 20230426.1 indicating this is not due to a change in the github runners (e.g. gdb version)

Copying from: #102 (comment)

The regression was introduced with oracle/graal#6504 and more specifically by oracle/graal@b70c640

It's also worth noting that oracle/graal@00eaa8e makes -H:-OmitInlinedMethodDebugLineInfo the default.

The above changes result in making the breakpoint appear in a different line (even with -H:+OmitInlinedMethodDebugLineInfo). Further investigation is required to see if this is an upstream issue.

[zakkak]

The regression is due to defaulting to not using SourceMappings when building the CompilationResultTree. This choice was made in order to improve build times, but as expected it comes at the cost of less accurate generated code to source mapping.

Building the native image with -H:+DebugCodeInfoUseSourceMappings brings back the old behavior.

This doesn't look like an upstream bug, but we probably want:

1. to add this flag to Quarkus when creating debug builds.
2. test both with and without the flag

@Karm @jerboaa thoughts?

This doesn't look like an upstream bug, but we probably want:

1. to add this flag to Quarkus when creating debug builds.

That seems fine. We'll have to add to the debugtest for the non-quarkus app as well, though.

2. test both with and without the flag

Like test it as two variations of the debug info tests? Not sure if it's worth it.
