Update of bug #48364 (project octave):

                  Status:               Confirmed => Patch Submitted        


Follow-up Comment #12:

The failing BIST is due to a bug in std::pow that we use from mingw-w64 [1].
The code in graphics.cc uses that function to calculate the axis limits for
logarithmic axes. The attached patch "fixes" the BIST by performing the same
operation in the test (powers of 10). So both are affected by the upstream
Since the aim of this test is to check whether the auto axis limits are
calculated as expected, I think that is the right thing to do here.

The change can be reverted, once the bug should be fixed in mingw-w64.
