CodeBlock crashes in Linux

tigerbeard:
For some time I keep seeing C::B crahes in Linux. Today I could now narrow it down to be quite reproducable on my system (I checked one PC and Laptop). I am using Build SVN12487 on Ubuntu 18.04LTS, gcc 7.4.0.

Here is the procedure to reproduce it:

Preparation:
1. Create a new Console Prokject with the default GCC.
2. Change the code to the following and save the project

--- Code: ---class CTest
{
void foo();
int nBar;
};

void CTest::foo() {
}

main()
{
return 0;
}
--- End code ---

1. Open the project. Select the Symbol Browser Tab and open CTest. It should show the function and the member variable
2. change: void CTest::foo() -> int CTest::foo()
3. Ctrl-S to save.
4. Double click on the symbol browser tree on "foo()" or "nBar"
I observed one of the following behaviours
a) ASSERT Window. The Backtrace includes "OnTreeDoubleClick". After the Assert windows I always get a crash with a few more clicks to various symbol tree items
b) crash
c) C:B hangs, so I have to kill the process.

I tried the same in the Windows version. There is no problem. I noted, that after saving the file in windows the tree is modified, this is missing in Linux. It seems that I can avoid the problem by re-parsing the tree every time.

Can someone please verify that on another system?

AndrewCot:
I followed the process as best I could and I did not get any crash. I would first suggest updating your C::B to the latest nightly build and try it.

My testing was done on the following:
XUbuntui 20.04 (updated yesterday)
C::B Nightly SVN-r12535 using wxWidgets 3.0.5

tigerbeard:
Thanks for testing.
Great new news that it seems to be a local item here.
Seems like I have an older Linux version 4.15.0 and also an older GTK 2.24.32 and runtime toolkit 2.24.

I will check the same build you are using.

That is selectable, look for Update parser when typing (on save otherwise) in Settings -> Editor -> Code Completion. Checking the option will increase CPU consumption, though.

tigerbeard:
I compiled the 12535, current nightly. Same behavior. I tested both checked and unchecked at "Update parser when typing (on save otherwise)" in Settings -> Editor -> Code Completion.

Could that be to GTK2? For compiling I used the system repository dependencies, i.e.

--- Code: --- sudo apt install libwxgtk3.0-dev libboost-system-dev fakeroot debhelper cdbs libgtk2.0-dev libgamin-dev libboost-dev libhunspell-dev
--- End code ---

and then

--- Code: ---./bootstrap
./debian/setup_control.sh
dpkg-buildpackage -us -uc
--- End code ---

The resulting debfiles I installed with
--- Code: ---dpkg -i *.deb
--- End code ---
