Silly me, mixed up the versions.
The behavior was observed in test project, but the version used there was 2.0.0.RC1. :)
A line "entry->state = DNS_STATE_DONE" was missing there, which caused dns_check_entry() to call dns_send() with illegal entry->pcb_idx. This was already fixed in 2.0.0.RC2 .
Sorry for inconvenience.
Best regards,
