[Jan Prunk <janprunk@xxxxxxxxx>]

Hello,

Please also send a CC: to 804079@xxxxxxxxxxxxxxx for future reference.

The administrator of the server is Andreas Ziegler <mail@xxxxxxxxx>,
maybe he will be able to log/reproduce the bug, I was only an initial reporter.

Kind regards,

Jan

The original bug report showed that there was a exception in the middle
of memcpy instruction while the latest log showed that the exception
could potentially be somewhere else.  Both logs showed that the
exception took place when ipv6 was involved.

If Jan can come up with a reliable repro I might be able to have a look.
