Segmentation fualt - core dumped on vesion 3.10.0

arnosk commented 4 years ago

Just installed the newest version 3.10.0 (64 bit) on my mini pc running Ubuntu 18.04.4 LTS And I am getting a segmentation fault. The previous version v3.0.0.0-32682b beta 64bit worked correct. Am I missing some libraries?

This is the backtrace:

The debug.log would also be helpful My initial thoughts on this are that the issue is with the wallet.dat. We have put a few additional checks in the wallet to verify integrity, and most issues we are seeing are where there is actually some level of corruption in the wallet.dat that wasn't detected with the earlier version, particularly with privkeys.

you seem to know your way around, so. Suggestion would be to

create additional backups of wallet.dat file
drop back to the earlier version of reddcoin core and start up,
take a note of wallet balance.
using either RPC or debug console,
- perform a dumpwallet to export all readable privkeys and their metadata
stop the reddcoin core
rename the wallet.dat (another backup)
your data directory should not have a wallet.dat file at this point as we want to start the new version and have a new wallet.dat file created
start the new reddcoin core (3.10.0)
use either RPC or debug console,
- perform a importwallet to import the previous dumpfile.
this should kick off a rescan at completion of the import
after rescan completes - check the balance matches expected

let me know how you get on.

I renamed the entire directory .reddcoin to test if the program would start up. But there was no new .reddcoin directory created. So no info in the debug.log. The program is hanging during the initialisation phase.

Ok, I have run up a vanilla VM of ubuntu 18.04 (64bit) copied the new binary from the download site, extracted and was able to launch the qt wallet successfully without error or segfault.

The distributed binary of reddcoin is statically built, however there are a couple of shared libraries that it depends

my guess is it is qt version 3.0.0 on linux required QT4 3.10.0 on linux moved to QT5 for all platforms

could you run ldd -r ./reddcoin-qt and post the output Thanks

Also, I have been making some assumptions, What was your actual installation method?

arnosk commented 4 years ago

I just unpacked the tar.gz file to a directory and run ./reddcoin-qt On my laptop (with Linux Mint 19.3 Tricia), I also had the same old version running, this worked out of the box.

The output off the ldd cmd is:

What was your resolution for this?

O sorry I accidently closed the issue (clicked the wrong button). It is not working yet
