Output hint in assertionEnded on assert

I've spent quite some time to figure out the crash occurring below when my app is built for CodeCoverage. It turned out that after refactoring, a helper method ended up in the test main which had a CATCH_REQUIRE with no test case. All tests passed, but finding that culprit took time.

Is it possible to print additional info about the likely cause, before the assert is triggered in assertionEnded()?

```
app-tests: /var/jenkins_home/workspace/build-fix/test/catch.hpp:5894: bool Catch::CumulativeReporterBase::assertionEnded(const Catch::AssertionStats&) [with DerivedT = Catch::JunitReporter]: Assertion `!m_sectionStack.empty()' failed.
