It's not possible to construct a path::string_type from an allocator of a different type. Create the correct specialization of basic_string, and adjust path::_S_str_convert to use a basic_string_view so that it is independent of the allocator type. PR libstdc++/94242 * include/bits/fs_path.h (path::_S_str_convert): Replace first parameter with basic_string_view so that strings with different allocators can be accepted. (path::generic_string<C,T,A>()): Use basic_string object that uses the right allocator type. * testsuite/27_io/filesystem/path/generic/94242.cc: New test. * testsuite/27_io/filesystem/path/generic/generic_string.cc: Improve test coverage.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
