Bruno, thanks a bundle!!!  I suggest this in lispbibl.d (so that I won't
have to reinvent the wheel every time I have a fault):

#define CHECK_MEM(msg) do { printf msg; gar_col(); } while(0)

the bad news is that the "suspicious code" is the innocently looking
call to allocate_dir_key()!

Bruno, do you mind looking at lispbibl.d?
