Is there nothing relevant above this line? Which compiler did you compile
with? If this is gcc 2.95, I suggest recompiling with gcc 3.3.

I have a hard time understanding this trace.

This appears to indicate an uncaught exception, which should not ever kill
PDNS in this case.

This is probably:

  if(mysql_query(&d_db,query.c_str())) 
    throw sPerrorException("Failed to execute mysql_query");

this is the 'outer' doQuery()

This is GSQLBackend::getUnfreshSlaveInfos()

This is the UeberBackend::getUnfreshSlaveInfos()
(...)

Now, the problem is, mainloop() should catch all exceptions thrown. So I
don't understand what happened.

Thanks.
