Development version occasionally crashes while editing schema (Page 1 of 3)

OK i start launching it with gdb.

I compile locally, as per https://wiki.mageia.org/en/QElectroTech
Is there something i can do to increase valuable output?

Right now i got a crash in *element* editor while by mouse changing the ovality of an arc, in a element i was modifying (so i have been deleting another arc and spossibly a line in it too, before crash)

I also an hour ago got the crash when saving after having deleted a line that was still visible, like in https://qelectrotech.org/forum/viewtopi … 5081#p5081 that you already know.

I use qt creator with gdb for debug and coding.

I have never used Qt Creator...
Is there some way i can compile qet to include debugging information?
(and then just easily run it in gdb)

Anyhow... i installed qt-creator, and opened qelectrotech.pro in the ...trunk folder, started debugging, and as excerise just closed QET  it to get the problem of previous post.  See screenshot below.

EDIT: OH, and there was also this in the Application Output window:
QObject::connect: Cannot queue arguments of type 'QVector<int>'
(Make sure 'QVector<int>' is registered using qRegisterMetaType().)
/EDIT

Do that tell you something?
What would you like me to do now?

Until answered i just try tu use QET as normal - run in debug this way, but i do not know how to get interesting parts when it crashes.

Now before reading the above post i was using it and the bug triggered: i deleted a conductor and made another conductor, suddenly the deleted conductor was visible again.
I could "select" it so it gets red with blue handles but can not do anything with it.
If i select and move an element the conductor is still shown like selected.
Moving an element on top of conductor deletes that covered part visually.
Then i decided to take a screen-shot, but on screenshot the whole deleted conductor is repainted, looking like normally selected.
I then decided to save the drawing (under new name): crash.

Opening the schematic it is correctly saved; the deleted conductor is not there, and the new conductor drawn after the deletion it there OK.

This may narrow down the problem searching a bit:
Interestingly, the Menu > "File" > "Recently Opened" list do NOT contain the new file.
So it crashed after saving everything to new file, but before updating wherever it stores that list.

Now i will try to make QtCreator debug show source code... (beginning by reading the above )
So far I have gdb (and also valgrind) installed and configured in QtCreator (at least correct executable paths)

EDIT: Note to self: also installed lib64qt5platformsupport-devel as i saw when started from terminal that QtDesigner was looking for libQt5PlatformSupport.prl  /EDITp, li { white-space: pre-wrap;

@ Morganol,

at this point, my knowledge is clearly "out of range"
Maybe a developer could say more about those debug infos.

Yes i have heard others complaining about Qt quality...

I will try to catch bugs with Qet source code.

Until then, clang do think there are at least potential problems with Qet code.  Have you checked?

( I am no programmer of this kind, so do not know much about it... just playing with the tools...)

Hooray, i caught a crash: https://qelectrotech.org/bugtracker/view.php?id=98
(a type i have not experienced before, but anyway...)

Great, Joshua
I am running 4736 in the same way now, will report if anything happens.
Please update Bug 98

Crash and other issues when editing an arc * REPEATABLE *
https://qelectrotech.org/bugtracker/view.php?id=101

Yes of course, and clang is very verbose.
It 's found ~ 45 warnings, only ~ 4 with GCC

I dont know if this is of any help, but this is output in the terminal from where i start Qet and load my schematic:
