Sorry for not finding the other two bug reports (for axis.m and assert.m). I agree then that this one is fully a duplicate and can be closed right away.

These test failures are also already recorded.

See bug #48364 for axis.m.

See bug #48365 for assert.m.

These bug reports are still open and unresolved, I think this can be closed as a duplicate. Any compelling reason for keeping this open?

I have installed the "official" Octave-4.2.0-rc3 Windows installer from alpha.gnu.org in its 64bit flavour on a Win7 system (I am not sure what kind of "64bit" is inside this installer).

I see the following failing tests:

  • publish.m as reported in bug #49501
  • eig.cc-tst as reported in bug #49470
  • Two more failing tests, which seem to be accuracy related (as bug #49470). They happen in "axis.m" and in "assert.m".


These are the relevant parts from fntest.log for those two "new" test failures:

I don't know if those test failures would also happen in a "64bit" built under linux.
