[Bug regex/788] New: re_comile_fastmap() will cause the 20 bytes memory leak

["dreamershl at gmail dot com" <sourceware-bugzilla at sources dot redhat dot com>]

When I use the fastmap in the regex. I find the memory leak. each time it will
cost 20 bytes. I check the re_compile_fastmap(). I find it seem this function
don't release the structure "fail_stack_type" memory. In the INIT_FAIL_STACK
macro, the fail_stack will get 5* sizeof (fail_stack_elt_t) bytes memory. but I
can't find the release statement at the end of the function.

int re_compile_fastmap (struct re_pattern_buffer *bufp)
{
  fail_stack_type fail_stack;
  ...
  INIT_FAIL_STACK ();
}
