5368.0. "SNMP MTU yacc stack overflow, again" by GWTEAL::WOESTEMEYER (Why??...Why not!!!) Wed Jul 21 1993 11:19

I have seen the yacc stact overflow before, but thought it was to be fixed
in V1.3.  Or was it fixed and just resurfaced again.  This is the third of 3
cabletron mibs. CTRON-COMMON-MIB, CTRON-OIDS, CTRON-RREV4-MIB(Repeater-MIB).

The no prune option was taken on all of these, and where applicable the augment 
option. 

The customer received these directly from Cabletron and tried to compile
then under V1.2 of decmcc where he got a different error:

  $ MANAGE/TOOLKIT/DICTIONARY LOAD FROM RREV4-MIB.COM

The customer also used the augment option where applicable.

Since I had seen this error in V1.2, I had him send the mibs to me so I could
try them under V1.3.  I got the following 'yacc stack overflow':

  $ MANAGE/TOOLKIT/SPECIFICATION CTRON_REPEATER_MIB.MS
DECmcc Management Specification Language Translation Tool
               Version V1.3.0

%MCCMSL-I-MSLLOCATION, Line: 1459, File: CTRON_REPEATER_MIB.MS;,
%MCCMSL-E-PARSER, yacc stack overflow: The value "1" is not expected
%MCCMSL-E-ERROR, MSL did not complete successfully, please see previous error
An error occurred while running the MSL Translator.
Check file CTRON_REPEATER_MIB.LOG, if it exists, for any further information.

Procedure terminated in error.

Any hints or ideas welcome, MIBS, MS files, etc availble on request.

	Steve,
		The MSL translator is overflowing its yacc stack while 
	processing MSL generated for the mib in question. I have forwarded 
	a copy of the problem report to Larry Grossman, who is more familiar 
	with the MSL translator. The default stack size probably needs to be
	increased.

	Rahul.
