Subject: Fix minor leaks in dhat.
X-Git-Tag: VALGRIND_3_16_0~301
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b4403d38c7242a26c50addfc7880f94b153ea7b9;p=thirdparty%2Fvalgrind.git

Fix minor leaks in dhat.

Only leaks in dh_fini, and only once.
But fixing these leaks is easier than maintain suppression entries.
