In theory this is http://trac.webkit.org/changeset/65573's fault, but that seems unlikely (it didn't touch that part of the code). from http://build.webkit.org/builders/Qt%20Windows%2032-bit%20Release/builds/6205/steps/compile-webkit/logs/stdio: ..\..\..\WebCore\dom\Document.cpp: In member function 'void WebCore::Document::addElementById(const WTF::AtomicString&, WebCore::Element*)': ..\..\..\WebCore\dom\Document.cpp:1140:6: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.

+Eric since James says he's interested in bot redness.
The right place is to file a bug with gcc. :)
(In reply to comment #2) > The right place is to file a bug with gcc. :) I was under the impression that the Qt build uses a particularly old version of GCC in a less common environment (MinGW) and so the bug may not be present in more recent versions.

Not at all, we ran into this bug more times earlyer with MinGW-4.4. And then I updated to MinGW-4.5, but this bug occurs now and again. Unfortunately we don't know what cause it, because sometimes a simple clean build or a machine restart solve the problem, sometimes not. :(
Now clean build solved this problem. But I don't know how can we fix it, because it might be a flakey gcc bug ...
