> hi. please turn on [-Xwatchconversion] and see which decision kills
it. this is rare but not impossible. Then, add backtrack=true and k=1
options to that decision to resolve. or restructure that decision.
I'm not sure I understand the answer.
When running 3.3 with -Xwatchconversion and -Xmx256MB, heap space runs
out and the output ends with the lines enclosed below. I gather that you
are saying that there is some way to map that info back into the name
space of my .g file but the specific means to do this escapes me.
For 3.2, the max DFA state is 575, by the way.
Cheers,
Rene
