It's possible this is similar to https://trac.sagemath.org/ticket/28106 simply insofar as some test is bumping up against the default 3300MB virtual memory limit imposed by the test runner. Which doesn't necessarily mean there isn't a problem: If some test is using a lot more memory than it used to, such that it's bumping up against that limit, there might be a leak or some other unintended memory usage consequence to the way a test was written.... -- You received this message because you are subscribed to the Google Groups "sage-release" group.
