Subject: malloc: Run tests without calling mallopt [BZ #19469]
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=124ea50584d3d21fe4c2fe9383508efd0ac9010a;p=thirdparty%2Fglibc.git

malloc: Run tests without calling mallopt [BZ #19469]

The compiled tests no longer refer to the mallopt symbol
from their main functions.  (Some tests still call mallopt
explicitly, which is fine.)
