Bug#834396: gnuplot-x11: assertion failure rotating splot with mouse

Mon Aug 15 07:50:11 UTC 2016

Package: gnuplot-x11
Version: 5.0.4+dfsg1-3
Severity: normal

Crash manipulating a 3d plot produced by the 'splot' command by rotating it with
the mouse. Usually takes less than 2 seconds of spinning to crash. This
particular sample crashed nearly immediately upon clicking the graph.

Here's a transcript of gnuplot under GDB:
