Ok, I didn't know that there could be null elements in the map. > Your code needs to be more defensive and check if tempMod is a nullptr > before dereferencing it.

When my program initializes, I do this swordLibrary = new sword::SWMgr(new sword::MarkupFilterMgr(sword::FMT_PLAIN)); and then pass a pointer to that around my various classes. In this particular function, the iterator is this, sword::ModMap::iterator libraryIterator; I had thought I was following one of the examples.
