Another interesting point - read.netCDF does *not* cause
R to dump core if debug(read.netCDF) is on. To be clear:

> rm(list=ls(all=T))
> library(netCDF)

# --- works ---
> debug(read.netCDF)
> fd<-open.netCDF("data.nc")
> z<-read.netCDF(fd,"foo")

--- lots of stuff deleted ---

> length(z)
[1] 143
--- what it should be

> close.netCDF(fd)
[1] TRUE   

#--- end works ---

That works fine.  Carrying on in the same session:

# --- doesn't work ---

> rm(z,fd)
> undebug(read.netCDF)
> fd<-open.netCDF("data.nc")
> z<-read.netCDF(fd,"foo")
Segmentation fault (core dumped)   

# --- end doesn't work ---

Now more puzzled.
