Re: [Plplot-general] strange bug in yplot

[Alan W. I. <ir...@be...>]

That's a strange one, Valerij.  All the driver details for yplot are just
handled by plplot so I don't understand why you get the segfault in one
situation (yorick front end = yplot), but not for the C front end to plplot.
This problem does not happen under Linux, and unfortunately I cannot proceed
further because I don't have access to solaris with X.  (The SF compile farm
solaris machine I have access to doesn't have X.)

If you wanted to investigate this further, I would try some variations on
the theme such as gcc rather than native solaris compiler (or vice versa
if these results were with gcc.)  Also, I would try the latest version of
plplot from CVS rather than 5.0.4.

Meanwhile, I will file this under bugs to be investigated if/when I get
access to solaris + X.
