KNOWN ISSUES
The test cases are currently failing with a TRAP Assert.
Unfortunately, the CI has failed to apply this patch for the last few
weeks, so any master changes during that time could have impacted VCI
without being noticed. Meanwhile, I am reposting these rebased patches
despite the known test issue, because then at least it may
catch/report any other emerging build problems early, while the cause
of the TRAP is still being investigated.
