Here when we went to mangle the constraints of from<0>, the outer lambda has no mangling scope, but the inner one was treated as having the outer one as its scope. And mangling the outer one means mangling its constraints, which include the inner one. So infinite recursion. But a lambda closure type isn't a scope that anything should have for mangling, the inner lambda should also have no mangling scope. PR c++/119175 gcc/cp/ChangeLog: * mangle.cc (decl_mangling_context): Look through lambda type. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/concepts-lambda23.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.
