What did you do?

Execute gomvpkg with some packages for refactoring purposes.

Something like:

gomvpkg -from github.com/socialpoint/<rest of the path> -to github.com/socialpoint<rest-of-the-new-path> -vcs_mv_cmd git mv {{.Src}} {{.Dst}}

What did you expect to see?

The command beeing executed properly.

What did you see instead?

note: second execution worked fine.

You say above that you are running Go 1.7.3, but the stack backtrace clearly indicates Go 1.6.2. What version did you use to build gomvpkg?

Is this repeatable at all? The address reported by the segmentation violation does not correspond to the stack trace.

It seems clear that mheap.lock.key is corrupted. It also seems clear that this is a binary built with Go 1.6. Go 1.6 is no longer supported.

Are you using macOS Sierra? That would explain memory corruption in binaries built with Go 1.6.

Regardless, please rebuild gomvpkg and any other binaries you have with Go 1.7, and please file a new issue (feel free to mention this one) if gomvpkg continues to crash.
