Are you running into a disk space limitation?  Remember, that
test_noninteractive generates something like 2GB of files and you could
quite easily get different results for different runs of test_noninteractive
under those circumstances.

Assuming it is not disk space or some other system resource running out, you
should always get the same build and test results for reliable hardware IF
you always have the same cmake configuration (environment variables and
cmake options), start with an empty build tree so there are no stale cache
issues, use the same source tree, and have unchanged dependent libraries.
Are your tests violating any of those conditions?
