Open Igetin opened 5 years ago

Igetin commented 5 years ago

Description of the problem or steps to reproduce

  1. Open a file you don’t have write permission to
  2. Try to save the file
  3. Answer “y” to the prompt: Permission denied. Do you want to save this file using sudo?
  4. The program crashes and prints a message like this: 
    
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xb code=0x1 addr=0x4c pc=0x236db8]

The crash only occurs sometimes. I have not been able to pinpoint the cause.

I’m using micro over SSH.
