Caused by unneeded pointer usages + not enough careful IPv6 porting
I haven't managed to reproduce the crash nor to test the fix due it
happening only when UDP relayed connection happens (apparently never on
my nodes.
I have managed to discover where the bug comes from thanks to multiple
user reports, specially to Ilario report which documented 3 crashes
happening on 0.6.4 with complete log.
