[Plplot-devel] How to PLplot (CVS sources, at least)

[Rafael L. <lab...@ps...>]

This simple program:

    $ cat crash.c
    #include "plplot.h"
    
    int
    main (int argc, char** argv)
    {
        plParseOpts(&argc, argv, PL_PARSE_FULL);
        plsdev ("xfig");
        plsfnam ("foo.fig");
        plinit ();
        plend ();
        plsdev ("png");
        plsfnam ("bar.png");    
        plinit ();
        plend ();
    }

crashes PLplot.  It says:

    $ ./crash -debug
    plLoadDriver: Device not loaded!
    plLoadDriver: tag=xfig, drvidx=11
    plLoadDriver: Trying to load xfig on
    /usr/lib/plplot5.2.0.cvs.20030219/data/../driversd/xfig
    Opened foo.fig
    Segmentation fault
    
It seems that this bug is related to a memory management problem in plend,
but I am not sure whether it has existed before I started changing the code.
If you have an old tree around, could you please test the program above?
