[antlr-interest] ANTLR 3.1.1 test failures

[Hartmuth Gutsche]

I just looked at the generated T.g file and that one looks like this:

grammar T;
options {output=AST;}
s : x+=a x+=b {System.out.println($x);} ;a : 'a';
b : 'b';
WS : (' '|'
') {skip();};


Which means that the problem shows up in the generated test grammar file.
Does the actual test generation have a problem?

Definitely such a kind of problem. One of the cases I am looking at is the
following:

...
public void testRuleLabelOnTwoDifferentRulesAST() throws Exception {
String grammar =
"grammar T;\n"+
"options {output=AST;}\n"+
"s : x+=a x+=b {System.out.println($x);} ;" +
"a : 'a';\n"+
"b : 'b';\n"+
"WS : (' '|'\n') {skip();};\n";
...

and what I find generated for mWS() in the lexer TLexer.java is:
...
switch (alt1) {
case 1 :
// C:\\DOCUME~1\\HARTMU~1\\LOCALS~1\\Temp\\antlr-1222999104471\\T.g:5:7: ' '
{
match(' ');
}
break;
case 2 :
// C:\\DOCUME~1\\HARTMU~1\\LOCALS~1\\Temp\\antlr-1222999104471\\T.g:5:11:
'\r\n'
{
match("               <<<<<<<-------
");                       <<<<<<<-------

}
break;
...


The "broken call" to match is of course what javac complains about with all
its consequences.
Any idea how to make that "unhappen"?
I still think is has something to-do with my environment setup I just don't
know what to look for.
Which environmental settings could possibly affect the generated code in the
above way?

Mostly likely \n and \r issue.
