[Pdns-users] wildcard throws signal 11

[Chris Seufert]

I'm having the same problem as described.


I tried with the Debian Etch i386 binaries, and have tried the sid 
source, back-ported to Etch.

Still no Joy

This is the backtrace i get:

gmysql-any-id-query=select * from vpowerdns WHERE data='%s' and siteid='%s'
gmysql-list-query=select * from vpowerdns WHERE siteid='%s'

host lookups for normal domains work perfectly, however wild card 
lookups kill it.

Any patch in the works, this is killing me.
