This restores support for std::make_exception_ptr<E&> and for using std::exception_ptr in C++98. Because the new non-throwing implementation needs to use std::decay to handle references the original throwing implementation is used for C++98. We also need to change the typeid expression so it doesn't yield the dynamic type when the function parameter is a reference to a polymorphic type. Otherwise the new exception object could be caught by any handler matching the dynamic type, even though the actual exception object is only a copy of the base class, sliced to the static type. libstdc++-v3/ChangeLog: PR libstdc++/103630 * libsupc++/exception_ptr.h (exception_ptr): Fix exception specifications on inline definitions. (make_exception_ptr): Decay the template parameter. Use typeid of the static type. * testsuite/18_support/exception_ptr/103630.cc: New test. |

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.
