I am hitting a possibly related issue. Unsure if I should open a separate report.

With current Dart Editor (Dart SDK version 0.6.3.3_r24898) my code started
to throw this exception:

NoSuchMethodError : method not found: 'Object [object Object] has no method 'computeSignature''
Receiver: ""
Arguments: []

The offending code is the call copy.forEach(_partTable.remove) from below:

    Map<String,Part> _partTable = new Map<String,Part>();

    // ... snip ...

    Iterable<String> keys = _partTable.keys;
    Iterable<String> filtered = keys.where((name) {
      bool empty = _partTable[name].indexListSize < 1;
      if (empty) {
        print("OBJ: deleting empty object=$name");
      }
      return empty;
    });
    List<String> copy = filtered.toList();
    copy.forEach(_partTable.remove);

This code works cleanly on the previous SDK (*) (with Dartium VM, dart2js and dart2js -c).

On the current SDK (**), the exception is thrown only with "dart2js -c".

Unfortunately I am unable to reproduce the issue with a standalone test case.

If you need any additional info to pinpoint this issue, please let me know.

(*) Previous SDK:
Dart Editor version 0.5.20_r24275
Dart SDK version 0.5.20.4_r24275

(**) Current SDK:
Dart Editor version 0.6.3_r24898
Dart SDK version 0.6.3.3_r24898

Tried the newer Dart Editor:

Dart Editor version 0.6.5_r25017
Dart SDK version 0.6.5.0_r25017

With this new DK, my code no longer throws the exception.
The offending code is unchanged though.
I'm clueless, unfortunately.
