 Hi,

 I'm unable to recreate it right now, but yesterday I was consistently
 getting a rather ugly `*** glibc ...` error which said something about an
 invalid double free().

 looked rather worse than a standard segfault and not something I've seen
 much of before. this is on the 20 month old version of Debian/stable and I
 haven't changed anything so expect glibc versions is as stable & well
 tested as it ever could be.

 the command line looked like
 {{{
    r.colors map1 color=bcyr -ae
 }}}

 the input map is gone now and I've changed r.surf.volcano enough
 that I don't get it anymore, but it can be assumed that there were
 0.0s in the map.  (-g blocks 0s but -a doesn't?)
