Immediately following the txid = line in the terminal is this:
1490779859 ERROR torsocks[2818]: Unable to resolve. Status reply: 4 (in socks5_recv_resolve_ptr_reply() at socks5.c:829)
Segmentation fault
Environment info:
Tails 2.11 Joinmarket 0.2.2 Bitcoin core 0.13.2
Running a full node with the blockchain source set to bitcoin-rpc.
wallet-tool.py and sendpayment.py -N 0 complete without errors.
Btw i was googling this error message earlier today and it seems to be associated with a gethostbyname call, see e.g. https://ubuntuforums.org/showthread.php?t=2250324
Also this one is from the same error: https://labs.riseup.net/code/issues/11736
Might just be noise but in case it's helpful.
Also spent some time with @griest024 on this and the error seems to be intermittent, seems some transactions did complete. Which makes it especially hard to know how to progress.
I should note that I do have AllowOutboundLocalHost 1 set. Setting it to 2 did not appear to help, but this is tricky to debug because I lose a little bit in fees every time I test something.
Setting rpc_host = 127.0.0.1 (as tailsjoin does, instead of localhost) does not resolve the bug.
@chris-belcher that is correct. program execution ends and I am returned to the prompt.
