Hello,
I am using SharedArrays to accumulate matrices that have been generated by different worker processes in my package Circuitscape. However, on windows, when I run the tests, I get:
Got exception outside of a @test
could not create mapping view: The operation completed successfully.
Stacktrace:

Any ideas on how to debug this? I don’t have an MWE, the easiest way to reproduce is to run Pkg.test("Circuitscape") on Windows. There’s an issue filed here
