Change to function call semantics in PHP 5.1?

In PHP 5.0.x, I can chain function calls like this:

$obj->method()->anotherMethod();

In PHP 5.1.x, this code results in an error:

parse error, unexpected T_OBJECT_OPERATOR in ...

I've looked through the change log for 5.1 but didn't see
anything relevant.

Was this an intentional change?

Thanks,
- Mark

What version did you try?  It seems to still work fine with current CVS.

Sorry, false alarm. I thought I had 5.1.2 in my path, but
it was actually 4.x.

jome@thisbe:~$ php -r 'class a { function b() { return new B; } } class
B { function C() { echo "Works fine."; } } $a = new A; $a->b()->c();'
Works fine.

jome@thisbe:~$ php -v
PHP 5.1.1 (cli) (built: Jan  7 2006 21:44:30)

The error is somewhere in your code.
