Code review comment for lp:~vanvugt/mir/fatal-error

Absolutely not. I've been doing core analysis from the wild for many years. And the most useless bug reports are always those from projects that try to do their own error handling/logging. Just don't do it. A developer with a debugger and correct symbols can always discover more from a clean core file. As can launchpad's automatic retracer.

With correct symbols (which is generally the hardest part, but feasible), you can analyse data structures by name and dive into all your variables in a meaningful way, post-mortem. It's just not feasible to know in advance what your crashes will be and which variables are the most relevant to debugging them. That's what core files solve.
