--- Comment #2 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:cf37107522f465d9e12af01ba68d2d1df0f18d46 commit r12-8213-gcf37107522f465d9e12af01ba68d2d1df0f18d46 Author: Jonathan Wakely <jwak...@redhat.com> Date: Thu Apr 21 11:26:49 2022 +0100 libstdc++: Remove bogus assertion in std::from_chars [PR105324] I'm not sure what I was thinking when I added this assertion, maybe it was supposed to be alignment == 1 (which is what the pmr::string actually uses). The simplest fix is to just remove the assertion. The assertion is no longer enabled by default on trunk, but it's still there for the --enablke-libstdcxx-debug build, and is still wrong. The fix is needed on the gcc-11 branch. libstdc++-v3/ChangeLog: PR libstdc++/105324 * src/c++17/floating_from_chars.cc (buffer_resource::do_allocate): Remove assertion. * testsuite/20_util/from_chars/pr105324.cc: New test.
