I'm getting Golang errors in my OSX terminal when I press enter multiple times. There's a known issue with OSX Sierra and Golang version 1.4.2. I don't have Golang version 1.4.2 but the stacktrace is referring to that so my assumption is that there is an application somewhere using the old version.
Is there a way I can enable verbose logging or find out the util/daemon that is causing the error? The stacktrace is below:
failed MSpanList_Insert 0x370000 0x672c197df0740 0x0
fatal error: MSpanList_Insert

(Moving my comment as an answer to mark this question as resolved).
Ended up fixing it. Manually went through my utilities and isolated direnv (github.com/direnv/direnv) as the problematic utility. I must have compiled it using old Go version.
Give brew upgrade go a try as this seems to be resolved in later versions, even if you didn't install with brew originally, the install path is the same so brew should solve it for you.
