            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
          Assignee: unassigned at sourceware dot org
          Reporter: korcankaraokcu at gmail dot com
  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 after
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 versions
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:

You're sending "interrupt"?  (BTW there's an MI command, "-exec-interrupt")

That probably won't work unless you've also requested MI
async mode, like "-gdb-set mi-async on".  Is your program
doing this?

I know the mi counterpart for interrupt exists, it's just that the code is old
and since it works, I haven't changed it

I've tried executing "-gdb-set mi-async on" before attaching and the result is
the same. I've also tested with regular gdb, without mi interpreter, outcome is
still the same

Btw, the more I tested, the more I've seen the other outcomes. In most of my
tests, the application crashed after the step 5 at the first try. I'm currently
testing on small games, Moonring on steam (proton) and Minesweeper on wine.
Moonring is free, test it for yourself if you want. Sometimes they just work as
usual, but mostly they just crash after step 5. I'll be changing the title to
reflect the other outcomes, such as crash
