Can this be right? valgrind seems to be saying that there are
double-free errors when I add this patch (see below).
Rather, use after free. The patch avoids the leak, but didn't do it
quite correctly. v2 coming up, and now I know why check-valgrind failed.
Sometimes, it's hard to see the actual error message because of
everything else that is also in the log.

But I also see you managed to get CFLAGS=-g propagated to the plugin in
this trace.
