MemoryError

[Denis Leonov]

You trying to parse Bitcoin data or may be some altcoin?

[Ziggy B.]

No, just Bitcoin. It also seems to happen at other blocks indexes.

[Denis Leonov]

Can you share this binary blk file? I try to check

[Ziggy B.]

I figured out the issue myself; I'm using an older Bitcoin-qt version (0.14.3). Because of this, the script sometimes returns an incorrect tx input script size (over 10GB) which causes Python to return a MemoryError. I'm not sure this happens with the newest version of Bitcoin-qt.

Bitcoin-QT version does not matter, sometimes all versions add to the binary data 1 strange 00 byte, that not documented anywhere
