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)
