Just got a:
could not launch process: invalid magic number in record at byte 0x0
When running on OSX after working fine for a while:
dlv debug main.go
reinstalled Delve, but still persists. What can it be?
The problem was the name of the package, I changed it and worked. Delve should give a better error message for that case.
Previously I had a custom name for the package name. After changing it to main delve started to work again.
