[Help-gsl] eigen test fails on 32-bit (x86) Linux

[address@hidden]

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]

I'm using GSL version 1.16, 32-bit Ubuntu 10.04 and GCC 4.4.3.

Best regards,
