crash when switching between groups #335

Mintulix · 2017-02-20T21:37:43Z

Expected Behavior

When switching groups with a mouse click or per keyboard, the entries of the selected folder should be shown.

Current Behavior

After a few group switches the application crashes and closes. When startet from command line, it just says "Speicherzugriffsfehler" or "memory-access-error".

Possible Solution

?

Steps to Reproduce (for bugs)

compile with parameters "cmake -DWITH_TESTS=OFF -DWITH_XC_AUTOTYPE=ON -DWITH_XC_HTTP=OFF .."
start keepassxc, create a few groups including a few entries
switch between groups a few times
for me it crashes after the 2nd or 3rd switch

Context

Your Environment

KeePassXC version/commit used: 2.1.2
Qt version (e.g. Qt 5.3): 5.5.1
Compiler (e.g. Clang++3.6.0): GNU 5.4.0
Operating System and version: Linux Mint 18.1 Cinnamon 64bit, latest updates

Are you doing anything else besides clicking on various entries in the group tree?
I am not able to reproduce the crash.

Mintulix · 2017-02-20T23:22:18Z

No, nothing else. How can I debug this to give you more information?
Just one other point: I didn't make a new database from scratch, but imported it from keepassx 0.4.4.
I didn't change the groups since then. Will make a new database and test it, but not today.

Try compiling with -DCMAKE_BUILD_TYPE=Debug and post here the stack trace.

By selecting groups I can't reproduce the bug either

That's not the stack trace.
You get the stack trace by running the keepassxc binary with gdb.

Open a terminal and run

gdb keepassxc

In the appearing input prompt enter run and then try to reproduce your crash. You get the stack trace by running bt after the crash.

This appears to be some deeper library problem on your system. It's not a KeePassXC bug.
Also these permission errors let assume that your GDB setup is somehow broken. I can't relly help you with this.

I would suggest you try our AppImage and see if that works. If you decide to compile it yourself, try using a different Qt version.

Mintulix · 2017-02-24T21:07:40Z

OK, thanks for analyzing. I will try again when I make a new system install in 1 or 2 months.
