Topic: Bitcoin-qt crash with solo mining (Read 1613 times)

Created a new topic there : https://bitcointalksearch.org/topic/assertion-failed-maincpp-line-1738-hashprevblock-viewgetbestblock-743134

Tried to set it up so that bitcoin-qt just mines by itself ( just as a test) : it crashes with
Assertion Failed main.cpp Line 1738 hashPrevBlock == view.getBestBlock()




 

bitcoin-qt should not crash regardless of how you've set it up. Assuming you have the latest bitcoind and this isn't coincidentally related to your bitcoin-qt being corrupted by a virus or otherwise, you should report this bug to the main bitcoin development team either via github or here: https://bitcointalk.org/index.php?board=6.0

yup, fully synced.
The config file contains server=1, so the server is up and running when I start the miner.
It mines for a few seconds / minutes ( depends), but then crashes.

Maybe I should try another pc, dunno, seriously lost here.

is your bitcoin-qt fully sync'd? are you running it with the -server command from a batch file?

ok, I'm a bit stuck here.
I start bitcoin qt, runs ok, until I start mining.
It mines for a bit ( few minutes tops, sometimes only a few seconds), and then Bitcoin-qt crashes.
It seems to happen right after a new block has been found on the network.


In the system application log, it only says it got stuck on msvcrt.dll, version: 7.0.2600.5512 on 0x00023509.

My bitcoin.conf :

datadir=e:\btc\data

I'm using bfg-miner:  mining seems to work (getting hashrate and stuff) , it's just impossible to mine since the bitcoin-qt always crashes.
Any thoughts on this one ?

EDIT:
 just tried it again. I let the client sync first (runs fine during that), after that I start bfg-miner, and it crashes. Last output from debug.log:

(Side note: I'm solo mining, it's a long shot (very long shot ;-)) since I only have an Antminer U1, but it's a fun little project ;-))
