Hi all, I'm about to release Bison 3.0.3, a long overdue bug fix release of the 3.0 series. Please, test it exhaustively on your projects!
Unless problems are reported, I will publish this announcement more widely in a few days. Thanks! Here are the compressed sources: ftp://ftp.gnu.org/gnu/bison/bison-3.0.3.tar.gz (3.2MB) ftp://ftp.gnu.org/gnu/bison/bison-3.0.3.tar.xz (1.9MB) Here are the GPG detached signatures[*]: ftp://ftp.gnu.org/gnu/bison/bison-3.0.3.tar.gz.sig ftp://ftp.gnu.org/gnu/bison/bison-3.0.3.tar.xz.sig Use a mirror for higher download bandwidth: http://www.gnu.org/order/ftp.html [*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify bison-3.0.3.tar.gz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys 0DDCAA3278D5264E and rerun the 'gpg --verify' command. This release was bootstrapped with the following tools: Autoconf 2.69 Automake 1.15 Flex 2.5.37 Gettext 0.19.4 Gnulib v0.1-334-g7585eb3 NEWS * Noteworthy changes in release 3.0.3 (2015-01-15) [stable] ** Bug fixes *** C++ with Variants (lalr1.cc) Problems with %destructor and '%define parse.assert' have been fixed. *** Named %union support (yacc.c, glr.c) Bison 3.0 introduced a regression on named %union such as %union foo { int ival; }; The possibility to use a name was introduced "for Yacc compatibility". It is however not required by POSIX Yacc, and its usefulness is not clear. *** %define api.value.type union with %defines (yacc.c, glr.c) The C parsers were broken when %defines was used together with "%define api.value.type union". *** Redeclarations are reported in proper order On %token FOO "foo" %printer {} "foo" %printer {} FOO bison used to report: /tmp/foo.yy:2.10-11: error: %printer redeclaration for FOO %printer {} "foo" ^^ /tmp/foo.yy:3.10-11: previous declaration %printer {} FOO ^^ Now, the "previous" declaration is always the first one. ** Documentation Bison now installs various files in its docdir (which defaults to '/usr/local/share/doc/bison'), including the three fully blown examples extracted from the documentation: - rpcalc Reverse polish calculator, a simple introductory example. - mfcalc Multi-function Calc, a calculator with memory and functions and located error messages. - calc++ a calculator in C++ using variant support and token constructors. _______________________________________________ help-bison@gnu.org https://lists.gnu.org/mailman/listinfo/help-bison
