Hi,
I built the Eigen 3.3-beta and ran the test.
Among the 779 tests, 5 of them failed.

Should I report it in the bug tracker? With what kind of information?

Sorry for these newbie questions...

Best.

Raf

you can simply past the list of failing tests here, some are known to fail, like bdcsvd_9 and fastmath with some clang versions. For the other, please run them manually to get the reason of the failure. You can also publish them to our CDash [1] by running "ctest -D Experimental".

I did the "ctest -D Experimental" stuff.
Also, here are more information about the failed tests, as requested.

Best,

Rafael
