-- Information about the crash:
- What I was doing when the application crashed:

I had clicked on an enum-type data member of a C++ struct.  Upon restarting, I can see that I may have accidentally removed the "r" from "struct", so perhaps that is the reason it crashed?

stuct my_crashy_struct {
    enum abc_abcd field1;
    /* some comments */
    struct abcdefg field2[2];
    /** some comment. */
    vector<enum something_t> field3;
};

I'm under NDA, so had to change names :(
