Subject: elogd crashes during Find and Mirror operations under MacOS 

When installing ELOG 3.1.2 on my Mac Sierra (10.12.2) with the latest XCode 8.2.1, it seemed to install fine but for one warning when building elogd:

cc -O3 -funroll-loops -fomit-frame-pointer -W -Wall -Wno-deprecated-declarations -DHAVE_SSL -I /opt/local/include -o elogd 
src/elogd.c crypt.o auth.o regex.o mxml.o  -lssl
src/elogd.c:13840:13: warning: '__builtin___strlcpy_chk' will always overflow
      destination buffer [-Wbuiltin-memcpy-chk-size]
            strlcpy(user_email, user_list[i], NAME_LENGTH);
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/secure/_string.h:105:3: note: expanded from macro 'strlcpy'
  __builtin___strlcpy_chk (dest, src, len, __darwin_obsz (dest))
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.

My installation was done with "sudo make install", as the instructions state.  I have also been using the prescribed "launchctl" approach.

1. Is the above warning something that needs attention/correcting?

2. My elogd crashes now every time that I attempt any kind of "Find" operation.

3. I synchronize my MacOS version of elog with a linux-based version on my university's web server.  I have installed 3.1.2 on the linux server, and it is running there without problems.  When I now try to synchronize my 3.1.2 ELOG on MacOS laptop with the same version on my linux server, it appears to do the first mirroring operation correctly, but elogd crashes when I try a second synchronization at a later time.  (For now, I have "Mirror simulate = 1" to prevent inadvertent damage.)

Can anyone help me with the above points?

Thank you,

Andreas
