This one's non-trivial, and I'd like a 2nd or 3rd pair of eyes. Only in an error condition, dbx_lookup_type mallocs enough memory for a pointer (struct type **), and uses it to return an error type. Many callers dereference this pointer, but it seems as if nobody ever saves it. And of course, nobody ever frees it. Using a static is not reentrant, but since nobody ever saves it, someone would have to make repeated calls to dbx_lookup_type very close to each other, while juggling return values, in order to get into trouble. This has been in there since version 1.1.
