Based on feedback from Intel, they are intending to emulate a gcc bug, when the gcc emulation version is 3.2 or less. However there is a bug in Intel 8 and 9 that means the bug emulation is always on, no matter what the gcc emulation version is. At some point Intel will probably patch this, but in the mean time can you test the following patch? Thanks, John.
