I am also using CC with 2.8.10 and it crashes or freezes from time to time. I have the impression that it is happening more often now... I have catch a few crashes and freezes and posted in this thread: http://forums.codeblocks.org/index.php/topic,13777.0.html
Year, when I use 2.8.10, C::B sometimes crashes, but I use 2.8.11 now, and C::B crashes very little...
I don't know why.
