Please file a tracker ticket. Generally anything that's an internal error
is likely to be a bug; even if the fix turns out to be a change to your
code, when there's a ticket the reproducing case ends up in the test suite
(which I'll push out to a public repository one of these days).
Make sure you document the command line (with all compiler flags, including
MCU selector) used when building the example.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
