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

Here are the compressed sources:   (4.1MB)   (2.1MB)

Here are the GPG detached signatures[*]:

Use a mirror for higher download bandwidth:

[*] 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 --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
  Gnulib v0.1-1882-g0d10473be


* 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

*** Portability fixes in the test suite

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