Brief Description of Problem:
-----------------------------
I try to parse a large grammar, but yacc core dumps. I have
extended the internal buffer with the N option to a very large number,
but as you can see that does not help.
(Parsing another grammar that is of small size works fine)
Please advise. (My ASAP number is D60972)

Lorentz, I have received your ASAP call as above. I can find no records of current problems with yacc, I will need more information to investigate your problem. Are you sure that the problem is caused by size, and not some incorrect statement in your yacc source? Can you e-mail me an example that causes the problem so we can repeat it? regards, Ian Chamberlin Ian Chamberlin, Digital Equipment Co, Software Partner Engineering. | |||||
| 3327.2 | Its a bug in yacc. | RDGENG::CHAMBERLIN | Danger! Do not Reverse Polarity | Thu Mar 20 1997 03:25 | 9 |
Received a copy of the source form Lorentz. Can't see any problems with the source - and it processes OK on Digital Unix V3.2C. Reported in OSF_QAR 52089. Lorentz will work round by using the yacc output from one of their other Unix systems. | |||||
