Hi,
I manage to reliably reproduce it !
1 Open attached project.
2 Double click MainMenu1 to edit
3 Under MenuItem5, delete MenuItem14,13,12,11
(I use the - button in the menu editor)
4 The last menu item under MenuItem5 is then 'Action3'
5 Add new menu item (I click 'add menu item' below the Action3 item)
6 Click on Action 3
7 Click on the newly added (in step 5) MenuItem11 --->> BOOM
Never fails.
The delete step 3 is important. Without that, I don't get a crash.
I then tested deleting a single item instead of 4 items as described
above,
then I also get a crash. So as soon as a delete is performed - boom...
Thank you for your exact explanation and test project! But sorry again,
again I don't get it.
I have tested here:
64bit Linux Mint 18.1 Cinnamon, GTK2 version 2.24.30, Lazarus 1.9.0
r54844 FPC 3.0.2 x86_64-linux-gtk2
64bit Linux Mint 17.3 KDE, GTK2 version 2.24.23, Lazarus 1.9.0 r54826
FPC 3.0.2 x86_64-linux-gtk2
64bit OpenSuse Leap 42.2 KDE GTK2 version 2.24.31, Lazarus 1.9.0 r54809
FPC 3.0.2 x86_64-linux-gtk2
64bit Windows 7, Lazarus 1.9.0 r54844 FPC 3.0.2 x86_64-win64-win32/win64
Maybe it is a problem with your GTK2 version?
Maybe it is a problem with your OS?
Maybe it was fixed in meantime?
Maybe you have a broken installation of Lazarus?
Maybe it is a timing problem (as my development pc was out of order, I
bought a relativ fast Core I5, so I'm not fast enough to click)?
Maybe it is better to open a bugreport about that issue? Then we can
better gather informations about it.
Is there anybody else how can create a crash with the test project and
the steps above?
