Fundamental genesis.print(); throwing a segment fault. #4153

Not changing anything, just trying to print the genesis block, it throws a segment fault (core dumped).

Can you elaborate in what you are doing exactly?

I've tested this many times before in previous 0.8 versions, and now when I try to print the genesis block (not changing anything), I get a Segmentation fault (core dumped)

doing the whole finding the find nNonce ==0 loop

    hashGenesisBlock = genesis.GetHash();
    while (hashGenesisBlock > bnProofOfWorkLimit.getuint256()){
        if (++genesis.nNonce==0) break;
        hashGenesisBlock = genesis.GetHash();
    }

chainparams.cpp -> genesis.print();

I see this method still exists in core.cpp so I know it's not a method taken out or no comments about it being deprecated...

Is this some altcoin-genesis-block-creating code? There is no genesis.print or genesis-incrementing nonce in Bitcoin Core.

It's used to re-create the BitCoin genesis block, yes... Thanks for verifying that there is no .print method in the BitCoin core. I thought that it might have been broken due to a change from 0.8 to 0.9

There is a print() method in CBlockIndex and CDiskBlockIndex. I still have no clue what code you're talking about, where the variable genesis is declared, what type it is, or where exactly it segfaults.

Thanks sipa,

It's the print() method in CBlockIndex that it's occurring.. I haven't tracked down on what line it's occurring.

I'll get back with that info...

I have to say guys, I'm very impressed with the responses and quickness that is represented here. Thanks for taking the time to look at this with me, even if it's just some benign occurrence that i'm experiencing.

Closing this unless you actually have a problem to report.
