Comment 15 for bug 1643911

valgrind would be great, but is the 100-pound gorilla approach. I'll play with maybe some lighter-weight things like electric fence which could give us some insight. something like that is going to segfault so we cores seem a top priority. I'm probably more optimistic about general usefulness of cores anyway ... sometimes in my experience dumping bits of the heap you can see strings or other things that give you a clue as to what's going on.
