Public bug reported:

It seems that whenever you call a glX* function from flgrx it doesn't
properly release memory it has allocated and cause massive
haemorrhaging.

this code (in c):
Display *xdpy;
XVisualInfo xv, *xvi = NULL;

xdpy = XOpenDisplay (":0.0");
if (xdpy != NULL)
{
    xv.class = TrueColor;
    xvi = XGetVisualInfo (p->xdpy, VisualClassMask, &xv, &n_items);
    if (xvi != NULL)
    {
          XFree (xvi);
    }
}

produces no errors and no memory leaks. whereas this code:

Display *xdpy;
XVisualInfo xv, *xvi = NULL;

xdpy = XOpenDisplay (":0.0");
if (xdpy != NULL)
{
    xv.class = TrueColor;
    xvi = XGetVisualInfo (p->xdpy, VisualClassMask, &xv, &n_items);
    if (xvi != NULL)
    {
          xcxt = glXCreateContext (p->xdpy, xvi, NULL, True);
          if (xcxt != NULL)
          {
              glXDestroyContext (p->xdpy, xcxt);
          }
          XFree (xvi);
    }
}

produces over 700 memory leaks. the valgrind --leak-check=full output is
attached
