[regression] 0.9.6 crashes when clicking "Example" as a first action

[okias]

$ flatpak install --user https://dl.flathub.org/build-repo/74697/cz.cvut.edu.comparch.qtrvsim.flatpakref
$ flatpak run cz.cvut.edu.comparch.qtrvsim

When you open the application and first action is clicking "Example" button, application silently crashes.

Works for 0.9.5 or when you press something else before pressing "Example" button

I am getting 404 with that link, could you check it?

With the help of bitect, I found out that the commit causing the problem is https://github.com/cvut/qtrvsim/commit/16c78c16948799a008b47569ea53989623c33e1f .

```text 16c78c16948799a008b47569ea53989623c33e1f is the first bad commit commit 16c78c16948799a008b47569ea53989623c33e1f Author: Jakub Dupak Date: Sun Jul 16 23:40:44 2023 +0200 GUI: split central widget tabs to coreview and editor src/gui/mainwindow/mainwindow.cpp | 17 +++++++++++------ src/gui/mainwindow/mainwindow.h | 3 ++- 2 files changed, 13 insertions(+), 7 deletions(-) ```

I have checked https://github.com/cvut/qtrvsim/commit/3dcd6963818c0f368d6ae5713d3b1b14f4d98217 whose everything's fine.

I have checked https://github.com/cvut/qtrvsim/commit/16c78c16948799a008b47569ea53989623c33e1f which causes an error during building process.

Qt 5.12.9 comes from Qt Downloads.

Compiler comes from mingw-w64.

I confirmed that the issue was successfully reproduced on Window on 0.9.6 .

After clicking the "Example" button for a while, the program crashes with nothing.

[okias]

Sure, it's building again. https://github.com/flathub/cz.cvut.edu.comparch.qtrvsim/pull/4#issuecomment-1911932988

Sure, it's building again. flathub/cz.cvut.edu.comparch.qtrvsim#4 (comment)

emmm I think it's a bug inside code. Rebuild this can't fix bug on Windows.

I think it is connected with https://github.com/cvut/qtrvsim/pull/73

[jdupak]

Agreed, I managed to reproduce it on Linux too now.

Sure, it's building again. flathub/cz.cvut.edu.comparch.qtrvsim#4 (comment) https://github.com/flathub/cz.cvut.edu.comparch.qtrvsim/pull/4#issuecomment-1911932988

emmm I think it's a bug inside code. Rebuild this can't fix bug on Windows.

Hi gods,

The file comes from action https://github.com/cvut/qtrvsim/actions/runs/7679651824 still cause troubles.

I tested target-Windows-qt5.12.9 and it crashes many times.

Here's the log.

text.log

I'd say that my own build on my Windows 10 works fine. So that might be some bug inside CI.

Hi, do you mean actual crashes (application window disappears) or just the text in console? I am asking, bacause I cannot see any problem in the log file you posted.

There is only (very detailed) information about execution, which is enabled only in debug builds. Everything not prefixed error or warning is fine.

@ArielHeleneto Oh, my apologies. You identified the issue correctly. I somehow missed the assert in your log. I am blind. Anyway should be fixed now. Tested on windows10.

Can you confirm?
