Question

Has anyone tried using the new record/replay and reverse-debugging features in the newly released gdb-7.0? I am one of the gdb developer/maintainers, and I'm very eager for user feedback!

Was it helpful?

Solution

Hi I tried it briefly. It make life a lot easier for the cases where either I screwed up some thing while debugging or for run-many-times-find-me bugs

OTHER TIPS

Well, there is now a tutorial to help you get started: http://www.sourceware.org/gdb/wiki/ProcessRecord/Tutorial

This definitely deserved more attention -- the reverse debugging feature ROCK FREAKING HARD. No sweat. Great work!

For a practical real-world use (and a problem with reverse-debugging), see

In GDB, how to find out who malloc'ed an address on the heap?

(Problem: it doesn't seem to support any IO (printf(), etc.) which makes it practically useless.
