Comment (by jhpalmieri):
Using the sage-5.0.beta10-gcc tarball from #12369, I get a doctest failure
on OS X Lion:
{{{
sage -t --long -force_lib devel/sage/sage/matrix/matrix_double_dense.pyx
**********************************************************************
File "/Users/palmieri/Desktop/Sage_stuff/sage_builds/GCC-no-
check/sage-5.0.beta10-gcc/devel/sage-
main/sage/matrix/matrix_double_dense.pyx", line 2843:
sage: B.is_normal(algorithm='naive', tol=1.0e-34)
Expected:
False
Got:
True
**********************************************************************
}}}
If I run this by hand, then even
{{{
sage: B.is_normal(algorithm='naive', tol=1.0e-300)
}}}
returns True.
