Subject: Call the destructors of the MCSections.
X-Git-Tag: llvmorg-3.7.0-rc1~3849
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=24d285d31ba07be9edff7788aa5003192dbbfb3a;p=platform%2Fupstream%2Fllvm.git

Call the destructors of the MCSections.

They now contain the fragments. If we don't call the destructors the
fragments leak.

Found by an asan bot.
