combinatorics coverage

[Ismael-VC]

I just screwed it up again, when trying to squash accidentaly merged something else, continues #11778 I didn't know how to fix it so I did the PR again, sorry for the inconveniences.

Why does this lines are not exercised even when this tests are defined and CI is run on both 32 and 64 bits architectures?

[tkelman]

The numbers that go to coveralls don't come from the same CI that tests PR's, they come from a separate 64 bit Ubuntu buildbot.

[Ismael-VC]

All right then. Travis tests are passing, only AV is left. I'll keep looking for chances to make more tests.

[Ismael-VC]

@tkelman couldn't we add something like this to the .travis.yml, script and after_success options, so we can have 32 bit coverage also?

[Ismael-VC]

Is there any documentation on how this build bots work?

[tkelman]

See the first post at #9493. The buildbot configuration lives at https://github.com/staticfloat/julia-buildbot and you can see the setup at http://buildbot.e.ip.saba.us:8010/builders. For measuring base coverage numbers, you have to do some custom configuration, run without inlining, and other modifications that are probably too slow to run on every travis build.

Thank you very much for all your help!

[tkelman]

No problem, test additions are great and always welcome. Thanks!
