flichtenheld. ( http://gerrit.openvpn.net/c/openvpn/+/1582?usp=email )
The following approvals got outdated and were removed:
Code-Review+2 by plaisthos
Change subject: Remove --with-mem-check=dmalloc
......................................................................
Remove --with-mem-check=dmalloc
This code hasn't compiled for years and noone complained.
We generally use ASAN instead.
So remove the dead code.
v2: The first version of this change tried to fix the
code. v2 instead removes it.
