(Windows 10) Crash on wake from sleep: memory access error

[taleinat]

Expected Behavior

When putting the PC to sleep and then waking it, the application should remain running.

Current Behavior

When waking the PC from sleep I consistently have the app crash. See attached screenshot for the error message.

Possible Solution

This this is easily reproducible on my machine and I am a programmer, I'd be happy to help pinpointing the source of the error, with specific guidance as to the steps to take.

Steps to Reproduce (for bugs)

1. Run KeePassXC on Windows 10
2. Open a DB
3. Put the PC to sleep
4. Wake the PC from sleep
5. On the lock screen, the attached memory error message appears

Context

I use a laptop for my development work, which I put to sleep and awake many times over each work day. Needing to restart KeePassXC and enter my master DB password is unnecessarily time-consuming, to the point of considering alternative solutions.

I have the same but does not happen every time. Today it is particualrly well-behaved and does not crash.
Otherwise, the crash happens on the login page where I have to enter the PIN to get back into the session.

Edit: In light of other comments, auto-lock is also set to happen when locking the workstation.

I get the same error when the database auto-locks itself after the set time.

Please run it in a debugger and reproduce the crash. I use kpxc in this exact same scenario and never experience a crash in resume or unlock. It might be something unique in your config and or database that is causing it.

Hey @droidmonkey, sorry for the late reply.

I consistently run into the error with the following steps (I'm not sure whether the issue is the same as the original one, but since I also get a memory error, I assume it's due to the auto-locking):

• PC turns on, auto-starts KeePassXC
• Press Ctrl+Alt+I to auto-type into a login form in the browser
• After the set auto-lock time passes (10 minutes in my case), KeePassXC crashes with a memory error

Please guide me on how to debug the error, I'll be happy to assist.

In the meantime, in case it helps, this is my keepassxc.ini file:

And my "debug info":

KeePassXC - Version 2.3.1

Enabled extensions:

- YubiKey

Some more info that I don't know whether is relevant: my key store file is located in a Dropbox folder.

I also suffer from this issue.
I've tried compiling a debug build, but the issue does not presents itself in this build. I used the following CMAKE arguments.
cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_VERBOSE_MAKEFILE=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -DWITH_GUI_TESTS=OFF -DWITH_XC_YUBIKEY=OFF

Maybe the issue is related to YubiKey?

Running the binary version in debugger gives the following information:
