Yes, of course exposure compensation can be used but the camera does this quite randomly. I would say 2-4 shots of a 36 roll can be overexposed.
Now, if I would set camera -1/2 stop or -1 stop underexposure then only 2-4 shots of film would be correctly exposed.
Check this pic, I put it on-line to demonstrate what I meant:
Those shots were taken with Canon EOS 300 on a same day, almost same time, using same film (Fuji Sensia 100) and no exposure compensation was used, shots were taken in cameras P-mode. You can see how washed out the white fuselage of the MD-87 (left pic) is, reg is barely visible.
This was almost the main reason why I bought the EOS 50E (Elan IIe in the US) which perfroms very well. Nowadays I use the EOS 300 only for prints so the overexposing-thing doesn't matter.
