API Doc: Gotcha: add section about 'exceptions to the rules' known crashing cases.

As exposed in T62406, we can have some rare cases of crashes due to
memory re-allocation happening outside of expected scenarii.

Ideally this should be re-designed, but at least keep track of those
known exceptions to general rules...
