bison-3.0.5 released [stable]

Item posted by Akim Demaille <akim> on Mon 28 May 2018 05:04:13 AM UTC.

We are happy to announce the release of GNU Bison 3.0.5, a bug fix
release.

Here are the compressed sources:
ftp://ftp.gnu.org/gnu/bison/bison-3.0.5.tar.gz (4.1MB)
ftp://ftp.gnu.org/gnu/bison/bison-3.0.5.tar.xz (2.1MB)

Here are the GPG detached signatures[*]:
ftp://ftp.gnu.org/gnu/bison/bison-3.0.5.tar.gz.sig
ftp://ftp.gnu.org/gnu/bison/bison-3.0.5.tar.xz.sig

Use a mirror for higher download bandwidth:
https://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-3.0.5.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 1.16.1
Flex 2.6.4
Gettext 0.19.8.1
Gnulib v0.1-1882-g0d10473be

NEWS

* Noteworthy changes in release 3.0.5 (2018-05-27) [stable]

** Bug fixes

*** C++: Fix support of 'syntax_error'

One incorrect 'inline' resulted in linking errors about the constructor of
the syntax_error exception.

*** C++: Fix warnings

GCC 7.3 (with -O1 or -O2 but not -O0 or -O3) issued null-dereference
warnings about yyformat being possibly null. It also warned about the
deprecated implicit definition of copy constructors when there's a
user-defined (copy) assignment operator.

*** Location of errors

In C++ parsers, out-of-bounds errors can happen when a rule with an empty
ride-hand side raises a syntax error. The behavior of the default parser
(yacc.c) in such a condition was undefined.

Now all the parsers match the behavior of glr.c: @$ is used as the
location of the error. This handles gracefully rules with and without
rhs.

*** Portability fixes in the test suite

On some platforms, some Java and/or C++ tests were failing.
