Hi,

It seems to be a very similar issue on my side on an amd64 file server.
this appends today after kernel update. not sure this is related.

I also have the same segfault on an i386 samba standalone file server 
since end of may with the following:

It seems to be worst/more frequent on the i386 platform. I had only one 
on the amd64.
Not at expert, let me know if additional data can help.
