Dear Tim,

A partial fix is a change to line 414 of database/DBcellname.c from:

	if (!strncmp(celluse->cu_id, "Topmost ", 8))
to:
	if (celluse->cu_id && (!strncmp(celluse->cu_id, "Topmost ", 8)))

This avoids the segmentation fault, although the "cell manager" window
gets a little confused and reports an error.  This script-level Tcl
error, however, is not fatal.

This error (and a number of others) has been corrected in magic-7.3.1,
which so far has been looking fairly stable to me, and seems to be
backwardly compatible with all the old tech files.  I changed the stacked
contacts code such that stacking types, which are unique to version 7.3,
can only be generated by being explicitly called out in the technology
file.

There remain a few instances of strange behavior with the stretching
mechanism in 7.3, but they are minor and I think I can resolve them
all eventually.

Thanks for the feedback.
