Jason Merrill 9718bc4b03 c++: array temporary at file scope [PR104182]
This is the same issue as PR104031, but that patch doesn't fix this
testcase because in this case, current_function_decl isn't set when we get
to cp_genericize_target_expr.  But there seems to be no need for
is_local_temp to check for function scope; !TREE_STATIC should be enough.

	PR c++/104182

gcc/cp/ChangeLog:

	* cp-gimplify.cc (cp_genericize_target_expr): Make sure nothing
	has set DECL_INITIAL on a TARGET_EXPR slot.
	* tree.cc (is_local_temp): Don't check DECL_CONTEXT.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/initlist127.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.
