    I'm using Magic 7.1 with SCN6M_DEEP.09 tech file version 2002a.  I find
that I'm able to overlap, for instance, a m1 poly contact (pc) with a
m123c contact and electrically connect poly to m3 without any drc
errors (see the example .mag file
http://www.csl.cornell.edu/~viran/test.mag )

I'm not sure if this is legal in Magic (e.g, if I try to overlap a m1 poly
contact with a via1, the via1 erases the pc layer).

Can anyone comment on whether this is a bug or not?

Thanks!
