+        * bidi.c (BIDI_CACHE_MAX_ELTS_PER_SLOT): New macro.
+        (bidi_cache_max_elts): New global variable.
+        (bidi_shelve_header_size): Add the sizeof bidi_cache_max_elts.
+        (bidi_cache_shrink, bidi_initialize): Reset bidi_cache_max_elts to
+        its initial value.
+        (bidi_cache_search): Handle overflown cache.  Improve commentary.
+        (bidi_cache_ensure_space): Limit allocations to the current value
+        of bidi_cache_max_elts.  Force xpalloc not to over-allocate.  If
+        less than a full BIDI_CACHE_CHUNK is left to the limit, decrease
+        the increment to not exceed the limit.
+        (bidi_cache_iterator_state): Now returns non-zero if succeeded to
+        cache, zero otherwise (meaning the cache overflowed).  In the
+        latter case, set bidi_cache_last_idx to -1.
+        (bidi_peek_at_next_level): Handle overflown cache.
+        (bidi_push_it): Increase the cache limit for iterating the new
+        object.
+        (bidi_pop_it): Decrease the cache limit back to previous value.
+        (bidi_shelve_cache): Shelve the current value of the cache limit.
+        (bidi_unshelve_cache): Restore the value of cache limit.
+        (bidi_find_bracket_pairs): If the cache overflows while looking
+        for the paired bracket, give up and let bidi_resolve_neutrals
+        process the bracket as a simple neutral.  (Bug#19322)
+        (bidi_find_other_level_edge): If the cache overflows, fall back on
+        Plan B, which effectively stops the reordering and restarts it on
+        the next character (after resetting the cache).
+        (bidi_move_to_visually_next): When the cache overflows, reset it
+        after processing the last cached character.

         Fix glitches in gnutls.c, mostly memory-related
