PARSER VERSION NUMBER: v7.0.0

PLATFORM (SPARC, HP700, PC, etc.): PC

OS AND VERSION: Windows 10

REPORTED BY: Arpad Muranyi; Mentor, a Siemens Business

DATE: November 25, 2019

DESCRIPTION OF BUG:
IBISCHK7 hangs when checking files such as bug208.ibs. This is a
simplification of the original test case provided by Arpad Muranyi,

An examination of source code shows that The bug is due to line 2928 of
imsmdl.c.  The continue statement there restarts the while loop without
advancing pNext to the next item.  Adding "pNext = pNext->pNext;" before line
2928 makes the program run successfully.

In the test case, two error are expected for missing bug208.iss and
bug208.s2p files.  If either of the [Interconnect Model] code is deleted,
ibischk7 terminates correctly with an appropriate Error message.

[Notes]          Test Case Hangs. If either of the [Interconnect Model]s
