While running my app testsuite I have another one which crashed. Fatal Python error: Segmentation fault Current thread 0x00007fe8d3527700: File "/usr/lib64/python2.7/site-packages/matplotlib/transforms.py", line 2370 in get_matrix File "/usr/lib64/python2.7/site-packages/matplotlib/transforms.py", line 2203 in get_affine File "/usr/lib64/python2.7/site-packages/matplotlib/transforms.py", line 2175 in transform_affine File "/usr/lib64/python2.7/site-packages/matplotlib/transforms.py", line 1238 in transform File "/usr/lib64/python2.7/site-packages/matplotlib/transforms.py", line 1030 in get_points File "/usr/lib64/python2.7/site-packages/matplotlib/transforms.py", line 277 in __array__ File "/usr/lib64/python2.7/site-packages/matplotlib/backends/backend_agg.py", line 110 in draw_path_collection File "/usr/lib64/python2.7/site-packages/matplotlib/collections.py", line 259 in draw File "/usr/lib64/python2.7/site-packages/matplotlib/artist.py", line 54 in draw_wrapper File "/usr/lib64/python2.7/site-packages/matplotlib/collections.py", line 695 in draw File "/usr/lib64/python2.7/site-packages/matplotlib/artist.py", line 54 in draw_wrapper File "/usr/lib64/python2.7/site-packages/matplotlib/axes.py", line 2086 in draw File "/usr/lib64/python2.7/site-packages/matplotlib/artist.py", line 54 in draw_wrapper File "/usr/lib64/python2.7/site-packages/matplotlib/figure.py", line 1006 in draw File "/usr/lib64/python2.7/site-packages/matplotlib/artist.py", line 54 in draw_wrapper File "/usr/lib64/python2.7/site-packages/matplotlib/backends/backend_agg.py", line 440 in draw File "/usr/lib64/python2.7/site-packages/matplotlib/backends/backend_agg.py", line 492 in print_png File "/usr/lib64/python2.7/site-packages/matplotlib/backend_bases.py", line 2096 in print_figure File "/usr/lib64/python2.7/site-packages/matplotlib/figure.py", line 1370 in savefig I wanted to draw 55620 dots in a scatter plot, each with a legend and its associated color. Actually only 100 color are used and multiple adjacent dots in the series have same color as necessary. Is this a matplotlib or a python error? |

Impossible to know, but since everything in the traceback comes from matplotlib, the error is most likely in matplotlib. |

Note that the same poster is also reporting memory corruption in issue 18843. I suggest ignoring this one unless/until the earlier bug is resolved (memory corruption can easily cause a segfault - or any other kind of error). |

I think this should be closed as extremely likely to be a matplotlib error. |

As issue 18843 has evolved, seems more likely now that it's flaky HW, but agreed in any case there's really no evidence of a Python problem here. So closing it. Martin, we can revisit this if there's real progress on the other issue. |

The issue could have been caused the malfunctioning memory or CPU. http://bugs.python.org/issue18843#msg204954 |
