Subject: Consider blocks with both SF_MMAP and SF_STACK set as part of the root
X-Git-Tag: svn/VALGRIND_3_0_0~162
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1afd856f3eded8e62dad594bee8e9af95b538123;p=thirdparty%2Fvalgrind.git

Consider blocks with both SF_MMAP and SF_STACK set as part of the root
memory set as any additional stack space allocated by valgrind will
have both flags set. This fixes bug #106293.
