Here, we capture nf, then the use of the proxy decays to a constant during semantic processing of +nf. Since we saw some decay from proxy to constant, we walk through the lambda body to see which proxies are still used, but we weren't walking into subtrees of DECL_EXPR at all, so we missed the use of &nf in the initializer of y, and removed the capture. But then at instantiation time we try to use nf, don't have a proxy anymore, and ICE. * lambda.c (mark_const_cap_r): Do walk subtrees of DECL_EXPR for non-proxy decls. From-SVN: r268471
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.
