Breakpoints not working. (linux)

[GAZ082]

Hey there. Stopped for a few weeks working on a Go project and when I returned to it noticed that when debugging the breakpoints do not work. I tested in a separate package a simple hello world program and when hit "debug test" in the generated test function for a fraction of a second the red got goes black and that's it.
