Hello, I noticed that eigen test fails on 32-bit Linux (x86) when compiled with -O3 flag:
$ ./configure CFLAGS="-O3" $ make $ eigen/test FAIL: gen, direct eigenvalue(4) imag, random (-0.481216772353650846 observed vs 0.481216772353650846 expected) [877968] FAIL: gen, direct eigenvalue(5) imag, random (0.481216772353650901 observed vs -0.481216772353650846 expected) [877970] FAIL: gen, direct eigenvalue(15) imag, random (6.85872455924790447 observed vs -6.85872455924790536 expected) [877990] FAIL: gen, direct eigenvalue(16) imag, random (-6.85872455924790536 observed vs 6.85872455924790625 expected) [877992] I'm using GSL version 1.16, 32-bit Ubuntu 10.04 and GCC 4.4.3.
