a bug in narcissus parser?

[George-36]

Hi ,
I happen to find that the narcissus parser seems bearing the following bug
about parsing windows-type end-of-line characters inside JS comments.

In spidermonkey, load narcissus engine by typing *load('js.js')*. Then
execute the following two lines of code.

parse('a=0\x0D\0Aa=1');     // works fine.
parse('/*\x0D\0A*/a=0');   // error: jsparse.js:172: SyntaxError: invalid
quantifier *
                                                   //
 jsparse.js:172: *

Is this a bug of narcissus code? If it is, how can I report this to Mozilla
developers?

Thanks,
Yan Huang

Hi Yan,

It looks like this is a bug (I don't see the regexp matcher allowing
backslashes in regexps). Can you report this at bugzilla.mozilla.org in the
"Core" product and the "JavaScript Engine" component?

Thanks.

Uh, of course when I said "RegExp" I meant "comment." Oops.

It seems not the backslashes in comments were causing the problem. Rather,
it is the carriage-return character '\r' that fails the parser. For example,

parse('/*\n*/a=1'); // parsed just fine

parse('/*\r\n*/a=1'); // fails
