           Summary: [Qt]REGRESSION(100375,100385): 32 bit build is broken
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: Qt, QtTriaged
          Severity: Critical
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ossy at webkit.org


http://trac.webkit.org/changeset/100375 and http://trac.webkit.org/changeset/100385
broke the 32 bit build on the Qt bot.

Unfortunately I couldn't comment the original bug, because there wasn't bug report.

The first build error caused by 100375:
../../../../Source/JavaScriptCore/dfg/DFGOperations.cpp: In function 'JSC::EncodedJSValue JSC::DFG::operationNewArrayBuffer(JSC::ExecState*, size_t, size_t)':
../../../../Source/JavaScriptCore/dfg/DFGOperations.cpp:782: error: invalid conversion from 'JSC::JSArray*' to 'JSC::EncodedJSValue'

I tried to revert 100375 locally (I had to resolve conflict manually), but I got the following errors:

../../../../Source/JavaScriptCore/dfg/DFGOperations.cpp: In function ‘JSC::EncodedJSValue JSC::DFG::operationNewArray(JSC::ExecState*, void*, size_t)’:
