PANIC!!!

[quchunguang]

I using sublime text and atom writing go code. Both of them get "PANIC PANIC" message any time i press '.' ! I removed them clearly and reinstall the newest version of gocode and sublime-text / atom with its packages but still not work.

Then look for other gocode binaries, it shouldn't panic really. Try running gocode in a separate terminal via: gocode close (to stop existing process) and gocode -s -debug. Paste here what it prints out on request.

I'm seeing this as well when building gocode wiht Go 1.8rc3

n/m, sorry for the noise. I had an older gocode binary in my path built with an older version of Go. The mismatch of versions I think was causing the panic I was seeing.

[ender-wan]

I have this problem before, and i solved it by gocode on debug mode, i found there a invalid .a(compiled package) file in pkg/, gocode parse this file failed, so i delete this file and reinstall my project, gocode works fine. hope this will helpful.

[yookoala]

I had the same issue after upgrade to 1.8. Also solved by debug mode. Also because of some previously built file in pkg.

With go1.11rc1:
