I am running a clean install of Monero client for Linux 64bit, binaries as available on 13-oct-2017, v0.11.0.0

I have deleted previous client, and ~/.bitmonero. I am importing an older wallet file though.

The blockchain synched for a few hours, but now whenever I run monerod it simply seg faults.

I have tried with monerod --block-sync-size=1 --max concurrency 1 but it still just dumps with a segmentation fault.

Any advice on how to fix this? Thankyou.

  • yes sure thing, very happy to help support monero. Just let me know what you need. FYI I just compiled fresh from github and it is syncing.

  • Just FYI: tried a manual import of blockchain.raw before this, that too failed with error 2017-10-14 00:46:55.545 7f727ffbe740 ERROR bcutil src/blockchain_utilities/blockchain_import.cpp:772 Exception at [Import error], what=Aborting

    Confirmed: resolves issue. Thankyou. Suggest: this patch should make it into the publicly available monero binaries as a matter of priority, to ensure a good end user impression. Compiling from source while trivial for those who know, is in practice simply out of reach of the many.

This crash was fixed in https://github.com/monero-project/monero/pull/2492, and you can merge it to your tree with the following commands:

git checkout -b crash-fix
git fetch origin pull/2492/head:2492
git cherry-pick 2492

You're now on a branch with whatever source you had before, plus the crash fix. You can now compile normally.

When you want to get back to master (ie, to pull latest):

git checkout master

  • Thankyou. FYI this crash occurs on the downloadable binaries from getmonero.org. Confirming building from source with current master resolves the issue.
