[lldb-dev] Do we have any infrastructure for creating mini dump files from a loaded process or from a core file?

[Leonard Mosescu via lldb-dev]

The minidump format is more or less documented in MSDN
<https://msdn.microsoft.com/en-us/library/windows/desktop/ms679293(v=vs.85).aspx>
.

That being said, it's not exactly trivial to produce a good minidump. Crashpad
<https://chromium.googlesource.com/crashpad/crashpad>has a native &
cross-platform minidump writer, that's what I'd start with.
