Test monetdb5/optimizer/Tests/dataflow.mal fails on all Windows & Solaris platforms of nightly testing, while working fine on all other platforms; cf., e.g.,
The point select is different between the two tests. This may indicate that the random number generator produced different results. Test expanded with explicit random seed.
Apparently, the random number generators on Solaris & Windows work differently than on other systems.
If despite the different random numbers and different behavior still tests what it's intended to test, we could consider approving specific output for Windows & Solaris (hope the behavior will remain deterministic over time).
Otherwise, we should consider redesigning the test without using mmath.rand().

Unfortunately, seeding the random number generator does not help; cf.,

The test now appears to work fine on all platforms.

This is about existing tests.
