Fill the error message using step by step known issues guidance.

{
  "ErrorMessage": ["MONO_ENV_OPTIONS=--interpreter", "Got a SIGSEGV while executing native code."],

Could be related to #114123

Two test logs, both System.Data.Odbc from the same commit:

• Test log dump
• Test log dump

Seems too consistent to be a coincidence.

@BrzVlad I don't recall seeing this crash before, can you take a look?

This is same issue as #101370. This is fixed on main, but didn't seem particularly important for a backport. 9.0.5 also manifests this crash.

[ericstj]

Not sure how common a customer application is to hit this, but typically crashing bugs like this meet the bar for servicing. I raised this because we didn't have a known issue tracking it and we need to be able to sort through the noise in servicing - these test runs are a big portion of what gives us a quality read in servicing where we have less folks using the builds before release.

[BrzVlad]

This issue would be reproducible if you have a PInvoke that fails to resolve. So, in practice, this is probably not a likely scenario since I guess it means you already have an issue with your application. I wouldn't consider it high priority, but we could backport it as well, the fix is low risk.

@BrzVlad could you please decide if we will backport this? If not, please close this.

[BrzVlad]

In my opinion it is not worth to backport the fix. I would still keep this issue open while net9 is active so it is referenced for failing builds. Alternatively I guess we could disable this test suite on interpreter, on net9 branch if you think this is a better approach.

[vitek-karas]

I'd be fine disabling the test - either a single test case if it can be focused, or even the whole suite if necessary. There's no value in running it as it will fail all the time.
