ge/sage/libs/fplll/fplll.pyx", line 853:
sage: L.echelon_form() == A.echelon_form()

The error also occurs with a 32-bit build on bsd.math (OS X 10.6, 5 out of
1000 runs) and on sage.math (64-bit Ubuntu 8.04.4 LTS, 6 of 1000 runs).
David Kirkby does '''not''' any failures on !OpenSolaris after about 15000
runs with 4.6.rc0 and about 15000 with 4.6.alpha1.
