Describe the issue

Can you reliably reproduce the issue?

If so, please list the steps to reproduce below:

  1. Download and install to /usr/local EMC 0.7.10 on m5.large machine with amazon linux 2 AMI
  2. Download blk-files to /home/user/.emercoin/blocks and make sure ownership and permissions are correct
  3. Create /home/user/.emecoin/emercoin.conf:
server=1
listen=1
txindex=1
rpcuser=user
rpcpassword=secret
rpcworkqueue=64
maxuploadtarget=144
  1. Run emercoind -reindex=1 -printtoconsole=1

Expected behaviour

I expect EMC to reindex blocks and start running.

Actual behaviour

Segmentation fault

What version are you using?

0.7.10 fails. 0.7.9 runs as expected.

Machine specs:

  • OS: Amazon Linux 2
  • CPU/RAM: m5.large
  • Disk size: 300G
  • Disk Type (HD/SDD): SSD

Any extra information that might be useful in the debugging process.

Sorry, didn't keep this one. :(

Same thing happens on my machine; like with constb 0.7.9 does work ok. My machine is Kubuntu 19.10 running on 5.0.0-38-generic x86_64 GNU/Linux.

  1. Try to remove all files, but wallet.dat (this is critical file, you need keep it), and re-download blockchain.
  2. Maybe, this manual will help: https://emercoin.com/en/news/chto-delat-esli-s-koshelkom-emercoin-chto-to-poshlo-ne-tak
  3. Use version 0.7.10

The workaround works but would be nice to have this investigated and fixed for a segmentation fault is not something desirable and upgrading would prevent downloading the entire block chain again.
