[antlr-interest] could not even do k=1 for decision 9; reason: timed out (>1000ms)

[Markus Lottmann]

Hi,

i try to create a c++ gramar and get the following error:

error(10): internal error: 
org.antlr.tool.Grammar.createLookaheadDFA(Grammar.java:1279): could not 
even do k=1 for decision 9; reason: timed out (>1000ms)

The problem is that the grammer contains a few hundert lines of rules 
and i do not know how i should find the rule
which corresponds to decision 9. I get this error not only for decision 
9 but multiple times.

Can anyone help me?

Greetings,
ML
