Bug ID: 44936 Summary: winedbg + gdb (remote) interaction broken due to recent commits Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winedbg Assignee: wine-bugs@winehq.org Reporter: julius.schwartzenberg@gmail.com Distribution: ---

I'm using OpenSUSE 42.3. I start winedbg as follows: winedbg --gdb --no-start path/to/smth.exe

Then I use Eclipse to connect to the remote port that is shown.

This results in: - ../../gdb/infrun.c:5585: internal-error: int finish_step_over(execution_control_state*): Assertion `ecs->event_thread->control.trap_expected' failed. A problem internal to GDB has been detected, further debugging may prove unreliable.

- Text I enter in the Debugger Console (in Eclipse) is invisible

- Things crash

When I revert back to 77d65c39486ffc2b4c17aec958e361b180a029a1 these problems disappear.

Please let me know if I should do more analysis.

--- Comment #1 from Zebediah Figura z.figura12@gmail.com --- Created attachment 61212 --> https://bugs.winehq.org/attachment.cgi?id=61212 gdbproxy debug

Thanks for the bug report; sorry it took so long to get to. I'm having trouble setting up Eclipse on my own machine, so I'm going to try to ask for debug output and see if that gets me anywhere.

Does this happen immediately, or only after setting a breakpoint? If the latter, can you try executing

...

set debug target 2 set debug infrun 2 set debug remote 2

and attach stderr from the server process (I hope)?

If the former it'll be necessary to patch winedbg to execute these on startup; I've attached a patch that should do this if you're willing and able.

While you're at it, could you also see if this patch makes the bug go away? Thanks.

--- Comment #3 from Julius Schwartzenberg julius.schwartzenberg@gmail.com --- Also my apologies, I had not been able to look into this more recently. I just tried this with Git revision 9fecb7499531ddbcde7970b4d98df92dbc1bc010 (currently origin/HEAD) without any patches and I cannot reproduce the issues anymore.

I now run into another problem however, the program I'm running just quits after I start it in the debugger. (It doesn't when ran without.)

I suspect this is unrelated however. Would it help you in general if I'd help you set up Eclipse? For this to work, you need to manually run 'winedbg --gdb --no-start' and use the printed port in Debug Configurations, add a Remote Application and on the Debugger tab->Connection tab fill in the port.

--- Comment #4 from Zebediah Figura z.figura12@gmail.com --- It was a problem with the package I was using (it kept crashing). I downloaded a more recent version directly from eclipse.org, and I can't seem to reproduce either problem. Following your instructions I seem to be able to attach to a simple test program, enter commands in the debug console, break and correctly step over breakpoints, and get output from the program. Perhaps it's something specific to the program in question?

Possibly. I'm trying to debug ABBYY Lingvo 12 http://web.archive.org/web/*/http://fr7.abbyy.com/lingvo12/ABBYY_Lingvo_12. exe

When I do not set any breakpoints I can see it the main window and then it suddenly exits (exited cleanly is printed).

I still can't seem to reproduce this, either with the installer or the program itself. It throws a lot of SIGABRTs, but otherwise the debugger works as well as if I'd started it from the terminal.

Do these problems show up for you if you just run 'wine winedbg --gdb foo.exe'?

--- Comment #7 from Julius Schwartzenberg julius.schwartzenberg@gmail.com --- Yes, I have the same issue then. I use these commands to let execution continue: handle SIGABRT pass nostop noprint handle SIGSEGV pass nostop noprint

Maybe that's not the right way?

I believe that's the right way, yes. I would guess that the program intends to catch these signals.

This is with Eclipse, right? It sounds like the debugger is working correctly then; can you help clarify what's failing?

Then did 'cont' to continue. Then I see the program pop up and then it just closes by itself.

Okay, thanks for bearing with me.

When I do this (with Lingvo.exe), the program shows a window saying "The trial period has expired for the following", and prompting me to activate or exit.

There are signs of bug 45070 when I close the program:

wine client error:8e: write: Bad file descriptor

but otherwise it works as I'd expect.

Is it something that only shows up after you activate?

--- Comment #11 from Julius Schwartzenberg julius.schwartzenberg@gmail.com --- Hmm, it never offered you a trial period? I indeed have a patched version which does not show this. Maybe that could indeed be the problem, I will try an unpatched version.

Can reproduce in wine 7.12 (staging) while debugging foobar2000.exe.

If this is still reproducible, can you please provide reproduction steps?

I don't recall exact reproduction steps. IIRC it has only happened ever once, and never appeared again.
