Re: [eigen] Eigen 3.1.0-beta1 released!

[Christoph Hertzberg <chtz@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

For that particular test (with that seed) I seem to end up in and 
endless loop (one repetition runs in about 1s; 3 repetitions do not 
finish within 15s (also not within a minute or so).
Build-type was DEBUG.

$ time test/qr_colpivoting_3 r1 s1339059513
Initializing random number generator with seed 1339059513
Repeating each test 1 times

real	0m1.076s
user	0m1.070s
sys	0m0.000s
$ time test/qr_colpivoting_3 r3 s1339059513
Initializing random number generator with seed 1339059513
Repeating each test 3 times
^C

real	0m15.090s
user	0m15.050s
sys	0m0.040s

$ gcc --version
gcc (Ubuntu 4.4.3-4ubuntu5.1) 4.4.3


I also very rarely experienced failed tests on product_trmm (I guess 
that's merely a question of precision):

$ time test/product_trmm_131 r1000 s1328456987
Initializing random number generator with seed 1328456987
Repeating each test 1000 times
Test (trmv<float, StrictlyUpper, ColMajor>()) failed in 
/home/chtz/workspace/eigen/test/product_trmm.cpp (72)
    test_isApprox(ge_sx_save - (ge_right.adjoint() * (-s1 * 
triTr).conjugate()).eval(), ge_sx.noalias() -= (ge_right.adjoint() * 
(-s1 * mat).adjoint().template triangularView<Mode>()).eval())
