I've got the same on
Maxima version: 5.15.0
Maxima build date: 15:9 6/10/2008
host type: x86_64-unknown-linux-gnu
lisp-implementation-type: CLISP
lisp-implementation-version: 2.44.1 (2008-02-23) (built on build12)
However sbcl works giving
(%i3) dgeev(E);
(%o3) [[5.918466822870407, .3419637922128298, 1.182773529427574,
2.283105468648542, 4.416178959415708, 3.09117658351303, 3.766334843911901],
false, false]
