A C/C++ IDE for OS X that isn't Xcode? I want a stable IDE for coding in C/C++ on Mac OS X Mavericks.

Currently I am using Code::Blocks but it sometimes closes reporting some strange list of errors. Also the Code::Blocks "logs(F2)" does some impairment to the editor area by leaving partial prints. I'm looking for an alternative now; can you suggest one?
The CLion cross-platform IDE by JetBrains for C and C++ was recently announced. It is only available as an “early access program” build right now, but when it’s stable, I’m sure it will be good. (Warning: it will cost money.) You might choose CLion over Eclipse for the same reasons you might choose JetBrains’ IntelliJ IDEA over Eclipse when programming Java.
