create-address-db.py crashes

[BTCBOY]

Hi.

I have a sync'd bitcoin-core node. I've stopped the node and run create-address-db.py, which crashes:

blk00976.dat Traceback (most recent call last):
  File "./create-address-db.py", line 72, in <module>
    addressset.create_address_db(args.dbfilename, blockdir, args.update, progress_bar=not args.no_progress)
  File "/root/recover/btcrecover/btcrecover/addressset.py", line 376, in create_address_db
    sigscript_len, offset = varint(block, offset + 36)      # skips 32-byte tx id & 4-byte tx index
  File "/root/recover/btcrecover/btcrecover/addressset.py", line 279, in varint
    b = ord(data[offset])
IndexError: string index out of range

In case it was a problem with the local bitcoin installation I resync'd it and tried again:

/bitcoind -daemon -reindex -dbcache=16384

shut it down cleanly and started again, but got the same issue (above).

I'm not sure what this is... could you upload blk00976.dat somewhere, e.g. Google Drive or Dropbox, and provide a link? (There's no private data in there, just raw Bitcoin blocks.)

I'm getting a very similar error, but no idea what the last block was... as it isn't showing on the windows commandline:

Parsing block files ...

On the off chance that it can help, I have uploaded my blk00976.dat for you here: https://www.dropbox.com/s/6g2np49w27cdk2o/blk00976.dat?dl=0

@HardCorePawn Thanks for that blocks file, I was able to reproduce a crash. I'll see what I can do....

I believe this should now be fixed, please let me know if you're still having trouble.

Thanks!

Amazing, worked well with this fix.
