It looks like you have a bad facility in the active_facility_list? I'm
not sure how this could happen, though. What's your config?

My bad - I added the format string to get a slightly different
traceback below (as I explained to Frank Filz, I originally had the call you suggest
without errstr, and got pretty much the same segfault). I'll keep exploring in gdb.
Advice appreciated. Thanks.

LogWarn() (and the others like it) are printf-alikes, so they need a
format parameter. It would be called like this:
LogWarn(COMPONENT_NFS_V4, "%s", errstr);
But, you don't need the errstr at all, you can just call like this:
LogWarn(COMPONENT_NFS_V4, "Invalid map: %s: %s", clue, line);
