Dear all,
Here the result I get when compiling from hg changeset 185e8dbdaa40
(very recent) on a Debian wheezy (7.8) x86_64 machine with "./configure
--without-OSMesa":
Summary:
PASS 12873
FAIL 1
XFAIL 14
SKIPPED 96
The log for the failed test is:
>>>>> processing

n = 4;
A = triu (rand (n));
x = rand (n, 1);

opts.UT = true;
opts.TRANSA = true;
assert (linsolve (A, b, opts), A' \ b);
!!!!! test failed

Has anybody seen this ? Perhaps should we introduce a tolerance for
these tests ?
