cuda tests fail for go version 1.10 and higher #224

Closed JeroenMulkers closed 5 years ago

JeroenMulkers commented 5 years ago

Running go test -vet=off -v github.com/mumax/3/cuda with go version 1.10 or higher yields the error message below. Consequently, the git commit hook, which runs all tests, fails as well.

--- PASS: TestBuffer (0.18s)

--- FAIL: TestReduceSum (0.00s)
