Codeblocks Crash

You can use Geany to write, edit, compile and run C++ source code. But if you want to use codeblocks, then please install the latest version of codeblocks 16.01. To install codeblocks 16.01 run this commands in terminal.

sudo apt-add-repository ppa:damien-moore/codeblocks-stable
sudo apt-get update
sudo apt-get install codeblocks

Try to disable symbol browser of code completion and see if the crushes stop.

Go to:

• Settings
• Editor
• Code Completion (on the left)
• Symbols browser

And check "✔ Disable symbols browser".

I had the same issue and this solved it.
