Summary: Implementation bug in the go client may lead to invalid state
Affected client versions: Latest (unpatched) versions of Go client; v1.1.2, v1.0.4 tags and develop, master branches before September 9.
Details: Go blog.nyoc client does not correctly restore state of execution environment when a transaction goes out-of-gas if – within the same block – a contract was suicided. This would result in an invalid copy operation of the state object; flagging the contract as not deleted. This operation would cause a consensus issue between the other implementations.
Effects on expected chain reorganisation depth: none
Remedial action taken by blog.nyoc: Provision of hotfixes as below.
Proposed temporary workaround: Use Python or C++ client
