9225.0. "YACC coredumps with large grammar" by RDGENG::CHAMBERLIN (Danger! Do not Reverse Polarity) Wed Mar 19 1997 08:39
A partner has reported yacc coredumping when trying to parse a large (1800
lines) grammar with yacc -vd <file> on Digital Unix V4.0B (rev 564).
He states the grammar works OK on at least three other (unspecified) Unix
platforms.
He has tried increasing internal strorage with very large N values (N9000000)
without effect.
I have looked at the source, and can't see any syntax/content problems, and the
fault reproduces on my V4.0A system. There are no error messages or anything. I
also tried with -s and that has the same problem.
I just tried it on a 3.2C system and it ran OK, without needing a large N value.
I swapped the skeleton parser drivers (/usr/ccs/lib/yaccpar) between systems,
using -P flag, and the v4.0 yacc still fails, whilst the V3.2C one still works,
so it looks like a problem with the actual yacc executable.
Has anyone any suggestions, or shall I QAR it?
Thanks,
Ian Chamberlin.
