Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start with tests/debuginfo/function-call.rs and the generated function-call.debugger.script, especially line 11, then reproduce the debuginfo-gdb failure using the logged GDB command. Compare the listed CI failures and CPU models to determine the conditions behind “Couldn't write extended state status: Bad address”; done means the test no longer fails intermittently in the affected configuration.
