[eigen] stablenorm test patch

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]


This fixes an error when running the stablenorm tests.
When talking with Benoit, he didn't have that problem, but it happened on my computer ( gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1, Intel Core 2 Duo T7300 with no SSE optimizations ).
The diff file is self-explanatory.
