PS. Thanks for all your work on golangci-lint, it's awesome!

[jirfag]

thank you for reporting, the crash was because of nil pointer to the logger in AST cache, I fixed it in #117,
update from master and re-run, please. But the issue isn't closed: there should be a warning printed and it's not ok. Attach this warning here, please.

[alecthomas]

Thanks! The source code has subsequently changed, so I can no longer replicate it :(

If I see something like it again I'll let you know.

[jirfag]

Ok, reopen or open new issue please when reproduces
