codeblocks randomly crashes when writing

[BomberKing]

i am using debian12.5 nighly version newly and now i am getting tired of codeblocks debug report problem,
this is what it looks like

i write some code and suddenly it says (debug report has been generated.
luckily the problem is able to reproduce.

i write cin then the code-completion shows me suggestions i click enter and everything is fine
but when i write cin without clicking enter
and then trying it again real fast the problem happens
i think this is related to code-completion

[BomberKing]

upd:
i disabled smart sense  from setting>>editor>>code-completion and it is working fine now,
i am wondering how to get code-completion working fine now

What CodeBlocks version are you using.
What OS are you using?
Can you show us your code that causes the crash?

[BomberKing]

i am currently using the lastest version on debian12.5 linux
it is not the code that caused the crash
it is writing it
while using SmartSense when i write "cout" without pressing enter
then writing "cout" again it crashes

but mostly when i write "ccin"  also it crashes

[BomberKing]

please help i am new to debian linux and trying to get something done

Are you using this work around for Wayland?
https://forums.next.codeblocks.org/index.php/topic,25206.msg171903.html#msg171903

As workaround I 'm launching codeblocks in wayland session  with

Code Select Expand


[luca@archer ~]$  GDK_BACKEND=x11 codeblocks

It seems the problem is related to wayland session, in X session there is not error.

If not try it.

but it gave a bit of help
it is now more flexible to that issue
but i can still make it happen

Something related to the wxScintilla control, because I see something here:

Code Select Expand

wxSCIListBoxWin::OnSize(wxSizeEvent&)

Something related to the wxScintilla control, because I see something here:

Code Select Expand

wxSCIListBoxWin::OnSize(wxSizeEvent&)

That looks llke the same error I fixed in rev 13473. It's caused by gtk3 issuing an OnSize() event that the original author (of our version of wxScintilla) did not expect.

The original author does not delete the codecompletion suggestion windows, but posts them to wxPendingDelete() queue instead. So there's no telling when the window(s) get deleted. Documentation says wxPendingDelete queue is run on the next available time. Who knows. I suspect either onIdle() or onYield(). Very dangerous. God-only-knows when the windows get freed.

The OnSize() code attempts to ask the ListWindow for an icon width, but the window evidently has already been freed.

The fix in cb rev 13473 cached the icon size so subsequent access to the window(s) pointer was no longer necessary.

The OP will need to update to at least rev 13473 to avoid this crash.

Edit: or maybe use one of the Linux's build for the nightly build.

i am using debian
i don't know why but the last version of codeblocks from apt is causing the crash
is there anyway to install  an updated version for me?

Report the problem and the fix to the Debian team and ask them to up date the package in sid.
Then install the updated sid package.

Edit: You should try the sid package before reporting the problem to the Debian team.

that's not what i meant
it would take ages to fix this for them

sorry for the inconvenience  i am newbie at linux and trying to get used
is there a simple way to install codeblocks without using apt ???

[BomberKing]

i sent issue info to debian team hope it gets fixed quickly
