PR117099 and PR117129 are ICEs upon invalid code that happen when NRVO is activated, and both due to the fact that we don't consistently set current_function_return_value to error_mark_node upon error in finish_return_expr. This patch fixes this inconsistency which fixes both cases since we skip calling finalize_nrv when current_function_return_value is error_mark_node. PR c++/117099 PR c++/117129 gcc/cp/ChangeLog: * typeck.cc (check_return_expr): Upon error, set current_function_return_value to error_mark_node. gcc/testsuite/ChangeLog: * g++.dg/parse/crash78.C: New test. * g++.dg/parse/crash78a.C: New test. * g++.dg/parse/crash79.C: 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.
