Subject: [vpp-dev] vpp crash in counter
I did download latest vpp from gerrit today to check if the crash is
reproduced and it is. I have used a debugged image to debug the issue. This
crash happens during testing of my plugin which is running IPv6 and the
plugin uses simple counters.
See backtrace() below.
