--- Comment #8 from Melven.Roehrig-Zoellner at DLR dot de --- Thanks for the quick replies and the discussion about the "not-so-usefulness" of the -dH switch (at least for our project). We most probably used this switch by mistake - you might possibly improve the documentation by adding "-dH Produce a core dump whenever a *compilation* error occurs." to prevent further misunderstandings for people who don't read the full paragraph.
