Qt Creator crashes parsing large files

If a file is suitably large enough after pre-processing, it will push a QByteArray to try and allocate an oversize chunk of memory, which will fail on Win/32.

Reproduceable by trying to parse qt sources via File|New Project|Other Project|Import existing project on the qt src tree.

File causing crash: "C:/Depot/qt/src/3rdparty/webkit/Source/WebKit2/WebProcess/WebCoreSupport/mac/WebSystemInterface.mm"
