problem with G_close_cell()?

[charnotw]

Hi

Does anybody know what might cause G_close_cell to give a bus error,
but only sometimes?

I'm using this function in my own program,  sometimes when it is
called I get a bus error, other times it works fine!  I have noticed
that as I continue with a GRASS session it fails more and more often 
until it fails all the time.  I then have to exit grass and start
again after which it is okay.

Any idea what might be causing it?

cheers  8-)
