[Plplot-general] plplot (fwd)

[H C P. <hc...@me...>]

Hi plplot people:

I think I found a bug in plplot which causes the xwin driver to die when
called from Fortran on Solaris 8. 

The bug is in this bit of xwin.c

/* Window title */

    if (plsc->plwindow){    /* jc: allow -plwindow to specify wm
decoration name*/
      sprintf(header, "%s", plsc->plwindow);
    }
    else 
      sprintf(header, "%s", plsc->program); /* jc: else program name*/

Now, when called from fortran, plsc->program is NULL at this point. In
Xfree86 on my Linux box, this just causes the window to have (null) as a
title, but on Slowaris, it causes a segfault. Yuk. One fix is as follows:

/* Window title */

    if (plsc->plwindow){    /* jc: allow -plwindow to specify wm
decoration name*/
      sprintf(header, "%s", plsc->plwindow);
    }
    else if( plsc->program){
      sprintf(header, "%s", plsc->program); /* jc: else program name*/
    }
    else
      sprintf(header,"%s","Plplot");

Enjoy! 

Hugh

P.S. I am wondering if this is the cause of some of the X weirdness on
Solaris reported by others.....
