Wallet crash on raspberry pi (3.7.5, 3.7.7 and 3.7.11.0)

[dduenker]

My wallet.dat seems to crash gridcoinresearchd, it dies with a segmentation fault, when it tries to load the wallet.
This happens as well on versions 3.7.5 and 3.7.7.

The same wallet.dat produces no crash on 3.7.7, when run on x64 linux.
The same happens with backups of the wallet.dat.

EDIT:
wallet.zip

OS: ubuntu mate 16.04

I will try to reproduce this on a fresh pi, is there other information i can provide?

[denravonska]

Hmmm, unable to produce on mine using my wallet.dat :( Will try from a 0-chain.

Edit: That worked as well. Let me know how your other test goes.

[Quezacoatl1]

I see a similar behavior on my pi 2, Ubuntu 16.04, 3.7.7.0
I tried syncing from 0 and from snapshot. I did not try without a wallet.DAT yet.

I believe the daemon dies in the end of the block loading process as it takes much more time for it to die if syncing from snapshot

[dduenker]

I did another test on a fresh installation of Ubuntu Mate 16.04 and Gridcoin 3.7.7.0, using my wallet.dat and had the crash again.
Would it help, if i gave access to my wallet.dat to a developer?

[denravonska]

It would help, yeah. If you feel uncomfortable sharing your main wallet, try to reproduce the issue with an empty wallet. Create a new wallet.dat on the same computer as your current one if possible, and then see if that dat can be used to trigger the error on the Pi.

[dduenker]

I noticed, that when i remove the optimization flag -O2 from makefile.unix, the resulting binary does not crash.

[iFoggz]

interesting. sounds like optimization problems?

I wonder if it's 32 vs 64 bit issues on int widths. Just speculating.

[tomasbrod]

I saw this on my pi.

[dduenker]

I just have this issue again with a freshly generated wallet.
Again it loads fine, when i compile gridcoinresearchd with -O0, but the binary provided in the ppa crashes.

I edited my first post and attached the wallet.dat, which crashes on my pi, as zip.

[jamescowens]

I believe this issue is resolved with newer builds. I am closing this issue. If it happens again reply to the issue and I will reopen.
