Details:

The second unit test in file src/mpfr_matrix_mul_d.cc of the octave-interval
package fails in a non-deterministic way.  The problem can be triggered like
this:


$ echo 'pkg load interval ; while 1 ; test("src/mpfr_matrix_mul_d.cc") ;
endwhile' | octave-cli -q 2>&1 | grep failed
!!!!! test failed
assert (time_per_element > 1.2 * time_per_element_parallel) failed


The patch attached to this bug report fixes the problem.
