There is some anti-spam trickery:
TO FILE BUGS, OR CHANGE THE WIKI, CLICK 'LOGIN' ABOVE, USERNAME anon
PASSWORD "No Spam" without quotes or the space in between '
So the password is NoSpam

We could probably boil this issue down to a tiny testcase that would crash
on NetBSD. This could then lead to a bugreport to NetBSD.
Can you try to compile this (g++ t.cc -o t):
#include <stdio.h>
class Bogo
{
public:
explicit Bogo(char a)
{
d_a = a;
}
char d_a;
};
__thread Bogo* t_a;
int main()
{
t_a = new Bogo('a');
Bogo* b = t_a;
printf("%c\n", b->d_a);
}
It is unlikely that PowerDNS will remove the __thread variables since they
work very well on all other relevant platforms ;-(
