PARSER VERSION NUMBER:
Found in IBISCHK3 V3.2.8 built for Windows 95
PLATFORM (SPARC, HP700, PC, etc.):
PC
OS AND VERSION:
Windows 2000 (Build 2195: Service Pack 2)
REPORTED BY: Matthew Flora, Innoveda, Inc.
DATE: 5 Feb 2002
DESCRIPTION OF BUG:
The parser seems to be getting confused by the file below. Several (28)
warnings are reported for the line which contains nothing but the [End]
keyword. (See first output.) What is bizarre is that if the Cref, Rref,
and Vref lines are commented out, then the number of warnings drops to 4.
(See the second output.)
With Cref, Rref, and Vref lines:
