It looks like something specific to the 4.6 series (I tried 4.4, 4.5, 4.6, 4.7 and 4.8 here), and this crash only happens when building in Release mode because only -O3 makes the compiler crash.

The GCC bug report KyungTae may be related, but it's about a 4.7.0 regression that does not crash 4.6 here.

GTK+ seems to require GCC 4.7.0, and my guess is that qmake doesn't pass -O3 in its equivalent to Release mode.

How about doing something like this in Source/WebCore/CMakeLists.txt:

# Detailed explaination of why we need this.
if (CMAKE_COMPILER_IS_GNUCXX) # Can restrict based on the version.
    set_source_files_properties(Modules/websocket/WebSocketDeflater.cpp
                                PROPERTIES COMPILE_FLAGS "-O2")
endif ()

This would end up passing -O2 to g++ at the end and fixes the issue.
