Well, the reason is simple. no_prefix is writing the passed parameter into a
static buffer, which is never reset. So you can't infinitelly call it
and have it
continue running.
Given that no_prefix is only called by init_switches(), you don't really
need
to call it again. It can be done once.

I'd place at the top of wget (char* param) a static bool initialised,
and replace

defaults() and init_switches() in that function with:
if (!initialised) {
  defaults();
  init_switches();
  initialised = true;
 }


Good luck
