Oh - I see. The simple workaround is to simply cache the pointer to said
structure and then free it. Like this:
int ggiWhateverDetach(ggi_visual_t vis)
{
int rc;
whateverext *we = LIBGGI_WHATEVEREXT(vis);
void *mypriv = we->mypriv; /* pointer still valid. Cache it. */
rc = ggiExtensionDetach(vis,ggiWhateverID);
GGIDPRINT("Detached Whatever extension from %p. rc=%i\n", vis, rc);
if (rc==0) free(mypriv);
return rc;
}
Solves it ?

No, it frees the extension struct - nothing more. Other stuff is up to the
extension itself.
