[Octave-bug-tracker] [bug #33249] log plots with all negative data produce segfault

[Rik]

Update of bug #33249 (project octave):

                  Status:                    None => Confirmed              
                 Summary: crash in loglog with negative x-data => log plots
with all negative data produce segfault

Follow-up Comment #2:

Confirmed on a recent tip (2011/05/07).  Interestingly, the problem is only
when *all* of the data is negative.  If there is some positive data, then a
warning message is printed (warning: axis: omitting nonpositive data in log
plot).  The fix lies in graphics.cc around the axis limit code.

This is a regression as the following code worked, i.e., didn't produce a
segfault in 3.2.4.


semilogy (1, -1)
