Swarm segmentation fault in network protocol on deplyoing chequebook

[5chdn]

System information

Geth version: geth 1.5.6-stable, swarm 0.2
OS & Version: ArchLinux, w/ kernel 4.8.13-1
Commit hash : n/a

Expected behaviour

• running Swarm on Ropsten testnet the first time in --swap mode
• deploying the chequebook contract
• profit

Actual behaviour

• running Swarm on Ropsten testnet the first time in --swap mode
• segmentation fault:

    panic: runtime error: invalid memory address or nil pointer dereference
    [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x5339d7]

• however, it seems the contract was deployed correctly:

https://testnet.etherscan.io/tx/0x7f940e418b2b0bb9f4de98e82e8aa968cf4ea9a0634f0c24ee9779f08a778ca4

• upon restart, it does not recognize the deployed contract

Steps to reproduce the behaviour

• running Swarm on Ropsten testnet the first time in --swap mode with the following parameters:

    0 ✓ user@ursae ~ $ swarm --swap --datadir ~/.ethereum/testnet/ --ethapi ~/.ethereum/testnet/geth.ipc --keystore ~/.ethereum/testnet/keystore/ --bzzaccount dcf407eae88d480e280db2d0deaa3a11c82eaa9b

• segmentation fault:

    panic: runtime error: invalid memory address or nil pointer dereference
    [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x5339d7]

• deployed the contract twice:

Maybe latest releases got this fixed?

I got same issue running ubuntu linux 16.04 on Virtual machine.
When I try to deploy chequebook on private blockchain.

[arokapil]

i am also facing similar issue

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x77bae7]

looks like its related with the Golang

[holisticode]

@arokapil thanks for adding to this issue. However, your stack trace is too small to be able to validate it is indeed related to the same issue or if it's due to something else. Could you please provide a more extensive stack trace (you may look at the original report above for what we are requesting)? Thanks

I am sorry but looking at this stack trace it seems unrelated to this issue. Please open a new ticket to report your problem. Thanks

[cobordism]

Closing this issue because Swap is currently being rewritten from scratch.
