Yes, my ATLAS have them. I am using ATLAS-3.3.13 and I didn't realize that
it may contain functions not included in the stable ATLAS. Sorry about
that.

Try using only flapack. Because the segfaults may be caused by the
1. issue above. To be sure that solve() will not use clapack functions,
you need to remove clapack.so file, commenting some test cases out may not
be enough.

So, shall we use benchmark_ or bench_ (instead of measure_) prefix for the
names of corresponding member functions in test_*.py?
