qtcreator 2.7.9rc-1 will crash with illegal instruction. This is likely due to missing SSE2 support on older CPUs, as this is a common issue these days.

What arch? I take it your processor is bound to i686? Since we compile with -march=i686, this sounds like an upstream bug.

Yes, it's i686. But it doesn't appear to be an upstream bug. The binary package from runs just fine. Maybe some qmake parameter is missing?
