It would be a good idea to check if the extraction was fixed between versions 7.1
and 7.3, by installing a version of 7.3 (locally, so as not to overwrite your
working version) and comparing the extraction results to 7.1.  If it's still
broken, I'd like you to send me an example layout that shows the behavior so
that I can debug it.

At this time, I have taped out a 5mm x 5mm chip in TSMC 0.18 and another
5mm x 5mm chip in Jazz 0.18 using magic-7.3, so it is at least as reliable
as 7.1.

True, it looks like magic is probably doing something terribly wrong, but
I like to make sure it's not driver error before I spend a lot of time
tracking down the problem (also, in this case, I want to make sure that
it's not something I already fixed between 7.1 and 7.2/7.3).
