--- Comment #12 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:24cf9f4c6f45f7d8b37757cdb34576ee5d2d40e1 commit r12-9454-g24cf9f4c6f45f7d8b37757cdb34576ee5d2d40e1 Author: Jonathan Wakely <jwak...@redhat.com> Date: Tue Mar 28 21:07:21 2023 +0100 libstdc++: Do not use facets cached in ios for ALT128 build [PR103387] For the powerpc64le build with two different long double representations, we cannot use the ios_base::_M_num_put and ios_base::_M_num_get pointers, because they might have been initialized in a translation unit using the other long double type. With the changes to add __try_use_facet to GCC 13 the cache isn't really needed now, we can just access the right facet in the locale directly, without needing RTTI checks. libstdc++-v3/ChangeLog: PR libstdc++/103387 * include/bits/istream.tcc (istream::_M_extract(ValueT&)): Use std::use_facet instead of cached _M_num_get facet. (istream::operator>>(short&)): Likewise. (istream::operator>>(int&)): Likewise. * include/bits/ostream.tcc (ostream::_M_insert(ValueT)): Use std::use_facet instead of cached _M_num_put facet.
