           Summary: Profiler causes javascript failures.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: petermayo at google.com


When I load a test page that works fine without profiling I get a javascript
exception.

Script debugging shows that one of the two arguments to a constructor is an
unexpected value.  Where I expect an instance of a class, the debugger reports
a reference to the constructor function.  The script bombs when the member
properties are missing, unsurprisingly, from there.

This problem is new as of r38386 - same page, same test works fine on r38209
and r38297.
