Subject: coroutines : Avoid a C++11ism.
X-Git-Tag: releases/gcc-10.3.0~219
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6c699f03c540d990b7e2a4f3813e16024598cab8;p=thirdparty%2Fgcc.git

coroutines : Avoid a C++11ism.

The master version of the code uses a defaulted CTOR, which had
been inadvertently backported to gcc-10.  Fixed thus.

gcc/cp/ChangeLog:

	* coroutines.cc (struct var_nest_node): Provide a default
	CTOR.
