I don't know how difficult this would be - as my bugs are all my own
work and I haven't needed to see your source code ;-) - but one of
the first things I build into any app is the internal logging /
fault reporting system.

Windows has such a reporting system on board - called WER (Windows
Error Reporting) ;-)

Well, we did introduce a similar mechanism with Automated Incident
Reports, which attaches the stack trace similar to what Windows error
reporting. I'd like to see what other companies have been doing with
the feedback - we use tools to analyze the stack traces over time to
find similaries which can let us track down faulty code.

The steps leading up to the error occuring are another thing. There can
be timing issues, project logic, memory management or a host of errors
not reflected in a stack trace that prevent the bug from being
reproduced.

Even per the suggesting sending an engineer over to the person's house
isn't always enough to fix the difficult to reproduce bugs - though I
agree it would be useful to clearly understand how/where it's occuring
and make a more effective investigation.

We already have a VMWare library of several terabytes of
configurations, that part is not difficult. The difficult part is
security.

We could just default to letting Nix use the current integration build
(no source code) to demonstrate the problem, which effectively is 'us
visiting him'. However, engineering can do a better job debugging with
availability of source. So at least we're considering that option with
the fallback being using a regular build.
