And release 16.04, which as a LTS replaces the LTS 14.04 > you use, also passes. Can you upgrade? That version of the openblas package is the latest currently available for 14.04 LTS from the official ubuntu repository. 14.04 LTS is "supported" by Canonical until 2019. Also, I'm just confirming that I can repeat it. It's not an issue for me as it's never happened other than the contrived example. If someone brought it to my attention, I'd probably follow your original though and ask them if they really wanted the determinant of an unassigned matrix as it sounds like not a useful thing to do. Using rnorm to initialise the matrix works fine. I'd suggest the OP pursue it with the linux mint people as it's directly affecting him and it occurs in their "supported" version.
