Re: Octave 3.5.92 snapshot available for ftp

Snapshot builds well and shows no errors with make check on openSUSE
12.1 (gcc 4.6.2)
and 11.4 (gcc 4.5.1) both 64bit.

A note for openSUSE 12.1 users:
When building against the umfpack from the science repository the
configure switch
--with-umfpack="-lumfpack -lcholmod -lcolamd -llapack"
was needed to succeed and arpack installed from
http://download.opensuse.org/repositories/home:/ocefpaf/openSUSE_12.1/
libarpack2-2.1-11.1.x86_64
libarpack2-devel-2.1-11.1.x86_64

for both versions (11.4 and 12.1) no skipped tests and 1 fail on 12.1
and no fails on 11.4.

On 12.1
Summary:

  PASS  10134
  FAIL      1

There were 2 expected failures (see fntests.log for details).

Expected failures are known bugs.  Please help improve Octave
by contributing fixes for them.

243 (of 803) .m files have no tests.

38 (of 154) .cc files have no tests.

The failed test in 12.1 is

  ***** testif HAVE_CXSPARSE
 n = 20; d= 0.2;
 a = sprandn(n,n,d)+speye(n,n);
 [c,r] = qr(a,ones(n,1));
 assert (r\c,full(a)\ones(n,1),10e-10)
!!!!! test failed
assert (r \ c,full (a) \ ones (n, 1),10e-10) expected
<skip>
maximum absolute error 3.678e-09 exceeds tolerance 1e-09

I will look what triggers that.
