I made the following experiment:

  . restore the calls to alloca -- the bug goes away

  . now add an xmalloc call to allocate a `struct charset_map_entries'
    right before alloca and an xfree call to free that memory after
    the call to load_charset_map, without doing anything with the
    allocated buffer in between the calls to xmalloc and to xfree --
    the bug is back!

So I think the change in charset.c itself did not cause the bug, it
just exposed a bug elsewhere, because it reshuffles the heap.
