Subject: libstdc++: Fix outdated comment in <stacktrace>
X-Git-Tag: releases/gcc-14.3.0~434
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2b9449c2c1b60ddc191d51617d892fa461b5cfcb;p=thirdparty%2Fgcc.git

libstdc++: Fix outdated comment in <stacktrace>

My r15-998-g2a83084ce55363 change replaced the use of nothrow
operator new with a call to __get_temporary_buffer, so update the
comment to match.

libstdc++-v3/ChangeLog:

	* include/std/stacktrace (_Impl::_M_allocate): Fix outdated
	comment.

(cherry picked from commit e8302282cdb53ae1d347c12d7a50c4209fbab4f7)
