This ICE appeared with the removal of NON_DEPENDENT_EXPR. Previously skip_simple_arithmetic would get NON_DEPENDENT_EXPR<CAST_EXPR<>> and since NON_DEPENDENT_EXPR is neither BINARY_CLASS_P nor UNARY_CLASS_P, there was no problem. But now we pass just CAST_EXPR<> and a CAST_EXPR is a tcc_unary, so we extract its null operand and crash. skip_simple_arithmetic is called from save_expr. cp_save_expr already avoids calling save_expr in a template, so that seems like an appropriate way to fix this. PR c++/119344 gcc/cp/ChangeLog: * typeck.cc (cp_build_binary_op): Use cp_save_expr instead of save_expr. gcc/testsuite/ChangeLog: * g++.dg/conversion/ptrmem10.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.
