gii bug + fix (?), (open close open close continued)

[Tijs van Bakel]

In lib/libgii/gii/gii.c, in the function

        int giiClose(struct gii_input *inp);

there is this code at the end of the closing loop:

                curr = curr->next;
                _giiInputFree(curr->prev);
        } while (curr!=inp);    /* looped through once. */

The call to _giiInputFree() segfaults if curr==inp, so I changed it
into this:

                curr = curr->next;
                if (curr != inp)
                  _giiInputFree(curr->prev);
        } while (curr!=inp);    /* looped through once. */

This of course works, but it's both ugly and I get the idea that
an input is not closed now.



Unfortunately this didn't solve the segfault I get when the simple
test program exits.  Again, here is a simple program that exits with a
segfault when run from the svgalib target:

#include <ggi/ggi.h>
int main()
{
  ggi_visual_t v;
  ggiInit();

  v = ggiOpen(NULL);
  ggiSetGraphMode(v,320,200,GGI_AUTO,GGI_AUTO,GT_8BIT);
  ggiClose(v);

  v = ggiOpen(NULL);
  ggiSetGraphMode(v,320,200,GGI_AUTO,GGI_AUTO,GT_8BIT);
  ggiClose(v);

  return 0;
}


Any ideas/hints/help ?
