Instant replay: Debugging C and C++ programs with rr (Red Hat Developer)

The Red Hat Developer Blog has posted anintroduction to the rr debugger. "rr records trace informationabout the execution of an application. This information allows you torepeatedly replay a particular recording of a failure and examine it in theGNU Debugger (GDB) to better investigate the cause. In addition toreplaying the trace, rr lets you run the program in reverse, in essenceallowing you 'rewind the tape' to see what happened earlier in theexecution of the program."
