There was another interesting sizeof problem with the V7 PDP11 compiler
(I dont know if it affected any others) whereby combinations of negation
and coercion applied to "sizeof" fell over. I cant remember the exact 
error but it was something like either 

    - (long) sizeof(int)
    (long) - sizeof(int)

The result was not properly sign extended from 16 to 32 bits.
I can dig out the exact details if anyone is interested.
