10195 Occasional doctest failure in libs/fplll/fplll.pyx mpatel mvngu "Reported on [http://groups.google.com/group/sage-devel/browse_thread/thread/145fb7e073d4e12b sage-devel]:

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''' get any incorrect results on !OpenSolaris 06/2009 after more than 15000 runs with 4.6.rc0 and more than 16000 with 4.6.1.alpha0. He had a total of 31748 passes. However, he did experience 109 doctest failures which are likely to be result of doctesting two copies of Sage simultaneously, as these were using the same directory for temporary files ({{{$HOME/.sage/tmp}}}). His errors were like this:
{{{
Run 442 of 100000
sage -t -long -force_lib ""devel/sage/sage/libs/fplll/fplll.pyx""
python: can't open file '/export/home/drkirkby/.sage//tmp/fplll.py':
[Errno 2] No such file or directory
[0.2 s]
}}}
and never due to False being return instead of True. His problems are probably the result of the issues discussed on #9739. Once David only tested one copy of Sage at a time, there were 0 failures in 17230 tests of sage-4.6.rc0. (Note, since Sage currently only works well on Solaris or !OpenSolaris if built as a 32-bit application, this was a 32-bit build).
