To reproduce the issue I have to include the test along with others and comment out "EIGEN_MAKE_ALIGNED_OPERATOR_NEW".  Upon seeing the segfault occurrences, (within the larger unit test framework), it is remedied by uncommenting "EIGEN_MAKE_ALIGNED_OPERATOR_NEW"

then yes, this is expected !!

gtest creates an instance of QuaternionTest through operator new, so you need EIGEN_MAKE_ALIGNED_OPERATOR_NEW !!

problem solved.

The fact it "works" with only one test is probably because the first call to malloc is properly aligned.
