Record, replay, and debug applications with Mozilla rr

Mozilla rr is a tool that you can use to record, replay, and debug applications. The main idea of Mozilla rr is to help you catch non-trivial bugs. The rr tool records a program execution. So later, you can replay the failing execution in the debugger as many times as you need.

From the Run menu in the gutter, select Record and Debug <configuration_name>.

Mozilla rr is available only on Linux machines.
