Hi all,

I have filed a test failure. The comment by Stefan was

#375: FAIL: check_syevr (scipy.lib.tests.test_lapack.test_flapack_float)
-----------------------+----------------------------------------------------
 Reporter:  nils       |        Owner:  somebody

Comment (by stefan):

 We should just relax the stringency of the test -- those results look
 good.


I guess this is also true for

======================================================================

Can someone reproduce the errors wrt odr ?
