Follow-up Comment #2:

What are the attached .rar files for? I was really too lazy to hceck them.

Anyway, the problem comes from checking for valid servers only in the
asynchronous path (where it is OK to call the found callback if no server is
left). In the synchronous path, I have changed the code to return an error if
no server is set, which should eliminate the only possibility to call the
'found' callback in direct call stack of 'dns_gethostbyname', so thi should be
fixed.

Thank for reporting, and thanks for the detailed report, which made it really
easy to reproduce the bug!
