greetings,

the following crash has me baffled. does anybody see what kind of 
mistake i am making to create this crash?

i am using SunOS 5.8 and
Erlang (THREADS,HIPE) (BEAM) emulator version 5.3.6.3


1> Fun = fun( Cfile, Acc ) ->
		io:fwrite( "Cfile: ~s~n", [Cfile] ),
		io:fwrite( "Acc: ~w~n", [Acc] ),
	        [Cfile|Acc]
	end,
Regexp = regexp:sh_to_awk( "*" ),
filelib:fold_files( "tmp", Regexp, false, Fun, [] ).

Cfile: tmp/a.c
