parameter types "l1", "l2", etc., for terminal lengths. There
was a string comparison against an unterminated character array
which was causing intermittant errors. This problem was masking
the incorrect handling of "l1", "l2", etc., parameters. The
parameter types had been introduced to cover a specific type of
drain-unsalicided FET in GF180MCU, which is used as an ESD
device in the foundry I/O cells, so the impact had been
relatively limited, although typically showed up as unexpected
property errors on the ESD devices when running LVS on a chip
top level. Both discovered errors have been fixed.
