The patch fixes a bug in the detection of the usage of static variables inside generic lambdas. The comment in finish_id_expression_1 already mentions this case, but the code didn't actually handle it. PR c++/114450 gcc/cp/ChangeLog: * lambda.cc (generic_lambda_fn_p): Handle null argument. * semantics.cc (finish_id_expression_1): Check for generic lambda. gcc/testsuite/ChangeLog: * g++.dg/warn/Wunused-var-42.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.
