That's strange...
I thought it was a random crash but I finally found the way to reproduce it...
I have a few variables defined in my code, every time I pass the mouse over some of them, the IDE freezes and starts using a lot of CPU and this seems to never end. The only way to exit the IDE is to terminate it in task manager.
I'm using Linux, Xubuntu 13.10. Don't know why this happens, but it already happened in older versions of Lazarus... Currently using 1.0.14.
Thank you!
