There was a problem hiding this comment.
I see no problem in:
- moving all default values to
BIP9Statsconstructor, or - moving these up even if they are overwritten below.

Or maybe just initialize the stats object with an = {}? |
Uninitialized data potentially used in `rpc/blockchain.cpp`:
```
static UniValue BIP9SoftForkDesc(const Consensus::Params& consensusParams, Consensus::DeploymentPos id)
{
...
const ThresholdState thresholdState = VersionBitsTipState(consensusParams, id);
...
if (THRESHOLD_STARTED == thresholdState)
{
UniValue statsUV(UniValue::VOBJ);
BIP9Stats statsStruct = VersionBitsTipStatistics(consensusParams, id);
statsUV.push_back(Pair("period", statsStruct.period));
statsUV.push_back(Pair("threshold", statsStruct.threshold));
statsUV.push_back(Pair("elapsed", statsStruct.elapsed));
statsUV.push_back(Pair("count", statsStruct.count));
statsUV.push_back(Pair("possible", statsStruct.possible));
rv.push_back(Pair("statistics", statsUV));
}
...
return rv;
}
