Hi,
I tried to look into this. The win32 port does not dump core, but
it does reprompt for when webserver is replaced by web-server or
web server. I have had it stuck in an infinite loop, but I'm
having difficulty recreating the problem.

At the center of the infinite loop problem is this function in
writeable.

static void soundslike_next(WordEntry * w)
{
  const Str * i   = (const Str *)(w->intr[0]);
  const Str * end = (const Str *)(w->intr[1]);
  set_word(*w, *i);
  ++i;
  if (i == end) w->adv_ = 0;
}
Nothing is changing w->intr[0] or w-inter[1] so w->adv is never
set to zero and the loop never terminates.

Also the WordEntry::intr array of void pointers is a bad idea in
my opinion. Is there any support for eliminating them?
