[Bug c++/36819] New: memleak in split_quote_chain

["wuhui1973 at 21cn dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The definition of the function is in c-inpath.c as following.
void
split_quote_chain (void)
{
  heads[QUOTE] = heads[BRACKET];
  tails[QUOTE] = tails[BRACKET];
  heads[BRACKET] = NULL;
  tails[BRACKET] = NULL;
  /* This is NOT redundant.  */
  quote_ignores_source_dir = true;
}

The elements in heads and tails point to the head and tail of certain list, and
the items in these lists are xmalloc in add_path. For above operation, memory
allocated for QUOTE list is leaked. Seems should invoke free_path first to
release the resource before the assignment.
This leakage will happen if we use -I- switch!
