+* data/skeletons/glr2.cc (yyundeleteLastStack): Recover
+yylookaheadNeeds stack entry also, to prevent desyncing the sizes
+of yystates and yylookaheadNeeds.
+(class glr_state_set): New field yylookaheadNeedLastDeleted,
+tracks lookahead need of last deleted state.
+(yymarkStackDeleted): Save yylookaheadNeeds also.
+---
+Hi!
+
+GCC 15 has added bounds-checks to vector<bool> when assertions are
+enabled.  This has caught a bug in Bison.  See bug referenced above.
+
+Now, WRT the fix: I am not sure of its correctness, but it appears to
+pass tests and everything seems to indicate that the presumption it is
+based on is correct.  That presumption is that the two stacks mentioned
+above (yylookaheadNeeds and yystates) ought to be the same size.  I
+inferred this because all other locations that alter the size of the two
+vectors appear to do so in lock-step.
+
+TIA, have a lovely day.
