I came across some unclear result when used callgraph to analyze go-ethereum project. Could you give me a clue to find an explanation, please?
I used these commands to generate reports:
1) rta analysis: callgraph github.com/ethereum/go-ethereum/cmd/geth > go-ethereum_call.txt
2) pta analysis: callgraph -algo pta github.com/ethereum/go-ethereum/cmd/geth > go-ethereum_call_pta.txt
Specifically, I cannot understand this line which appears in both reports: (github.com/ethereum/go-ethereum/log.funcHandler).Log --dynamic-36:10--> github.com/ethereum/go-ethereum/log.StreamHandler$1
This is supposed should be called here: https://github.com/ethereum/go-ethereum/blob/a9835c1816bc49ee54c82b4f2a5b05cbcd89881b/log/handler.go#L36
What is the reason that such dynamic call could occur and in which case it is possible?
