To re-run this test, run:
dart pkg/front_end/test/unit_test_suites.dart -p pkg/front_end/test/fasta/text_serialization/extension_types/type_variable_in_static_context
The test has outcome Crash, but was expected to have outcome(s) {ExpectationFileMismatchSerialized}. You might have to update the status file to the new outcome
There's a status entry looking something like
extension_types/type_variable_in_static_context: ExpectationFileMismatchSerialized
which should be updated.
The status file is file:///opt/s/w/ir/pkg/front_end/testcases/text_serialization.status.
cc @athomas - possibly flakiness is infra related
According to @whesse this is flakiness in the CFE or the tests, moving to area-front-end.

@whesse We are seeing this from time to time. Do you have any idea what can cause this?

This failure in random tests is happening in the package testing and pkg/front_end/test/utils/kernel_chain.dart front end testing system.
If the "git diff" command run by Process.run fails or crashes, then the test is shown as a failure. There could be better handling of a failure of this command to run, perhaps showing the stderr from the process, and marking the test step as an infra failure, not saying that this single test has failed.
StdioProcess process = await StdioProcess.run(
"git", <String>["diff", "--no-index", "-u", expected.toFilePath(), "-"],
input: actual, runInShell: true);
return process.output;
There is already a workaround on Windows for this subprocess call, because it is flaky on Windows.
