[ragel-users] Ragel 6.8 broken in Go

[Anton Ageev]

Hello.

I can't reproduce this case:

$ ./ragel-6.8/ragel/ragel -v
Ragel State Machine Compiler version 6.8 Feb 2013
Copyright (c) 2001-2009 by Adrian Thurston
$ ./ragel-6.8/ragel/ragel -Z -G2 main.rl
$ go version
go version go1.1.2 linux/amd64
$ go run main.go
DGT: 1
DGT: 2
DGT: 3
DEC: .
DGT: 4
DGT: 5
DGT: 6
SGN: +
EXP: 7
EXP: 8
EXP: 9

It seems you use ragel 6.7 or older.
