--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:a54ce8865a885bca5ab9c4aa6ec725cd13c09901 commit r12-5193-ga54ce8865a885bca5ab9c4aa6ec725cd13c09901 Author: Jonathan Wakely <jwak...@redhat.com> Date: Wed Nov 3 16:06:29 2021 +0000 libstdc++: Print assertion messages to stderr [PR59675] This replaces the printf used by failed debug assertions with fprintf, so we can write to stderr. To avoid including <stdio.h> the assert function is moved into the library. To avoid programs using a vague linkage definition of the old inline function, the function is renamed. Code compiled with old versions of GCC might still call the old function, but code compiled with the newer GCC will call the new function and write to stderr. libstdc++-v3/ChangeLog: PR libstdc++/59675 * acinclude.m4 (libtool_VERSION): Bump version. * config/abi/pre/gnu.ver (GLIBCXX_3.4.30): Add version and export new symbol. * configure: Regenerate. * include/bits/c++config (__replacement_assert): Remove, declare __glibcxx_assert_fail instead. * src/c++11/debug.cc (__glibcxx_assert_fail): New function to replace __replacement_assert, writing to stderr instead of stdout. * testsuite/util/testsuite_abi.cc: Update latest version.
