            Bug ID: 31359
           Summary: Unable to stop proton or wine games after a breakpoint
                    gets triggered
           Product: gdb
           Version: HEAD
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: breakpoints

  Target Milestone: ---

After a breakpoint hits, it becomes impossible to stop the process again. I=
'm
generally using gdb with mi interpreter so I've also tried it with the
interrupt command, it doesn't work either. Here's the reproduction steps

1-)Attach to a wine/proton game
2-)Stop the process
3-)Set a breakpoint at $pc
4-)Continue the process, the breakpoint hits immediately
5-)Remove the breakpoint and continue the process

There's a good chance the process will never react to interrupt command aft=
er
the steps 3-5. If it works, try repeating steps 3-5 again. In my experience,
this happens either in 1st or 2nd try. I've tested with multiple gdb versio=
ns
including 11.2, 12.1 and 14.1 and I was able to reproduce the bug so I've
chosen HEAD as the version

I'm using the mi interpreter to automate gdb for pince. Here's the related
github issue for anyone interested:
