[Bug 1670304] Re: Samba smbd [4.3.11-Ubuntu] segfault? 'panic action' backtrace

[Nish Aravamudan]

Hello,

Thank you for filing this bug report. Unfortunately, just given a
backtrace, it's rather difficult to determine what is happening. Is this
a reproducible issue? What are the steps to reproduce it? Ubuntu 14.04
or 16.04?

** Changed in: samba (Ubuntu)
       Status: New => Incomplete
