I'm trying to parse blockchain using parser https://github.com/znort987/blockparser but it throws an error (segfault) on block #488466.

Did anyone have the same error and how to overcome it?

P.S Ran with "./parser allBalances" param on Ubuntu 14 64Gb RAM, 32 cores

yes, that is old peice of software., it doesnt work anymore. read this  https://github.com/znort987/blockparser/issues

and this

https://github.com/znort987/blockparser/issues/65

install bitcoin-core-0.11.2 and do rescan on whole blockahain and then try to run

./parser allBalances

and see if it works., theriotically it should from above references.

That sw is like what 4+ years old, and it will just bog down around 400k blocks, and certainly there would be a core crash, they even caveat to tell you to have 32gb of RAM on your system, as all their work is done in malloc()

The problem here is this sw is 4+ years old, and if the github is even a month since the last update, chances are 99% it aint' going to work, its the nature of BTC sw, ... because core is always changing the block-chain format, and nobody is going to maintain the shit for long, cuz you would go nutz

...

Said it before and will say again, if you want to parse bTC you must write you  own parser, its not hard, only ten lines of python to parse, what most ppl here are after, the problem, is that its clear that most here aren't programmers, and that is where the rubber meets the road,

Just like this post about a seg-fault, a programmer, would have just just used GDB and resolved the problem, but not here no way, there are no programmers.

there are lots of programmers here.,

but why reinvent the wheel ? there are already libraries/apps on internet to do the job., besides learning constantly changing bitcoin-core is not easy task.

I am also interested in this topic. Can you please list some of the most reliable and maintained tools for parsing the blockchain for different purposes?

Thanks
