Worked for 24 hours and then crashed? Weird. But thinking of it, this
could be one of the reasons why its not crashing *here*. Every 24 hours
my ISP cuts the connection, and our router gets a new IP and 'dnsmasq'
restarts!

So as I understand you, its related with the DNS servers you use!? With
your ISP servers, it crashes and with the german servers, it doesn't?

Ok, solution found - that was easy... ;-))

But as long as I'm working on this, I'm more and more sure that these
intermediate crashes are really a combination between the DNS servers
and 'dnsmasq' itself. Sad to say, I haven't got the (C-)skills to debug
this.

Right now, I'm trying to compile 'dnsmasq' with patches 051-053: it now
crashes in 'forward.c' during compilation if I activate the
DNSSEC-option (-e 's|/\* #define HAVE_DNSSEC \*/|#define HAVE_DNSSEC|g'
\). Reason: patch No.053, I think.

In contrast, the '2.76test6'-version compiles without *any* error, if I
delete and disable *all* of our adjustments.

As Simon wrote: "Conditional combination has a nasty combinatorial
explosion. I should hack up a regression test to build all possible
variants."

But obviously this wasn't done yet. If I leave everything as it is, its
building...

Perhaps I'll try another request on the dnsmasq-list during the next
days. The last one had no effect, no answers, nothing.

Best,
Matthias
