Long time compiling the ragel file after small change

[assism]

Hello
i have a ragel file that among other things contains something like :
`
.
.
.
dq = """;
nl = ("\n" | "\r" | "\r\n");
tripleQoute = dq dq dq;
blockstring = tripleQoute (any - tripleQoute)* tripleQoute;
simplestring =
dq
(any-dq-nl)*
dq ;

stringvalue = simplestring;
.
.
.
.
}%%`

if i change the stringvalue to be : `
stringvalue = simplestring | blockstring;

`
, the time to compile it increase very dramatically.
(not in this simple example, but within all of my file) compiling time on linux machine goes from 12 sec to 10 MINUTES,
on windows i stopped it after half an hour or so without result. the memory consumption of the process also increase to about 16GB.

i'm using ragel 6.10

is there any reason to this time issue ?
