octave with USE=sparse fails at computing [1 1; 1 0; 0 0] \ [1; 0; 0]... Reproducible: Always Steps to Reproduce: 1. # USE=sparse emerge octave 2. $ octave 3. octave:1> [1 1; 1 0; 0 0] \ [1; 0; 0] Actual Results: ** On entry to DLASDA parameter number 2 had an illegal value ** On entry to DLASDA parameter number 2 had an illegal value error: exception encountered in Fortran subroutine dgelsd_ Expected Results: ans = 7.7048e-18 1.0000e+00 0. The test above fails at the same time with [ 0.50374 0.61402 0.43301; 0.60290 0.78609 0.43301 ] \ [ -1.0531; -1.0531 ] obtained from http://comments.gmane.org/gmane.comp.gnu.octave.general/31243 . That discussion seems to be related to my problem. 1. Failure does not reproduce if USE=-sparse. 2. Switching between lapack and blas implementations (atlas/reference) has no effect. 3. Manually installed official tarball octave-3.2.4.tar.bz2 does not fail (run ./configure with no options). Tarball does not fail even if I pass the same configure options as portage does: cat /var/tmp/portage/sci-mathematics/octave-3.2.4-r1/work/octave-3.2.4/config.log |head -20 |grep ./configure 4. I hope I've found the way portage hurts octave: when running ./configure, it sets LDFLAGS="-Wl,-O1 -Wl,--as-needed" (along with other options). That options seems to have crucial effect on official tarball on my boxes: ./tar xf octave-3.2.4.tar.bz2 ./configure; make -j12; echo '[1 1; 1 0; 0 0] \ [1; 0; 0]' |./run-octave # works fine LDFLAGS="-Wl,-O1 -Wl,--as-needed" ./configure; make -j12; echo '[1 1; 1 0; 0 0] \ [1; 0; 0]' |./run-octave # fails as described 5. On my box, official octave 3.3.53 fails the same way as gentoo's octave-3.2.4 (unless arpack is disabled when configured). However, octave-3 is not in portage now :) Tested with sci-libs/lapack-reference 3.1.1-r1, sci-libs/lapack-atlas 3.8.0, sci-libs/blas-atlas 3.8.0, sci-libs/blas-reference 20070226, sci-libs/arpack 96-r2.

Could be an as-needed issue with arpack. Assigning to maintainers.
A small fix in arpack-96-r2 for the lapack dependency should fix this: + 24 Jan 2011; Sébastien Fabbro <bicatali@gentoo.org> arpack-96-r2.ebuild: + Added missing lapack dependency, fixed some as-needed requirements for + parpack in the patch, fixed a test. Also should fix bug #352602 and bug + #345713 +
I've updated world up to portage tree 2011-02-06 on x86 box and rebuilt arpack-96-r2 with new portage on x86_64 box. Both tests on both boxes pass. Thank you.
