Bugs at Savannah

[Tim Landscheidt]

Hi,

with 2.5.1 on the horizon, a look at the remaining bugs on
Savannah (https://savannah.gnu.org/support/?group=bison):

- "Testcase #50 failing non-deterministically for bison
  2.4": I assume this was fixed by 47fa57; at least
  lib/subpipe.c is gone anyway :-).

- "Updating to bison 2.4 breaks WebKit": This seems to have
  been a duplicate of
  http://permalink.gmane.org/gmane.comp.parsers.bison.bugs/3078
  and solved on WebKit's side per
  https://bugs.webkit.org/show_bug.cgi?id=22205.

- "YYPOPSTACK used inconsistently": The user infers from
  yacc.c to "garbage collected environments".  The code in
  lalr1.cc looks fine.

- "--no-parser and %no-parser option is broken": Probably
  "Wont Do".

- "ambiguity problem with bison GLR parser": The reporter
  initially misread the manual.

- "Possible bug in overflow handling": After staring for
  half an hour at yacc.c's code paths, I think this is not a
  bug (and hope that saving a few bytes is really worth the
  very "special" memory management Bison uses :-)).

- "parser stack overflow handling + documentation on it":
  The bug's title should be "Document yyoverflow()".

- "C++ template makes it very difficult to override func-
  tions": This is probably a matter of taste.
