Bug Description

The C implementation of xenstored in xen-4.1.6.1 is missing commit de8c3e826499dbf69d01ee935a67b5d67a131496 from xen-4.6:
  tools/xenstore: Correct use of va_end() after va_copy()
This leads to data corruption which only triggers very rarely; we were never able to reproduce it in our test environment, but we had crashes of xenstored nearly each month.

For reference here's the issues from our bug-tracker: <https://forge.univention.org/bugzilla/show_bug.cgi?id=35104>
