With the v1.3.0-rc2 I was able to compile qt4-x11 (one make job) with no
problems. After I tried to compile the package six times in parallel (also one
make job) I saw that some of the compile jobs ended up in an ICE at
random points.
So I thing there is also some instability with v1.3.0-rc2 but it is
harder to trigger.

I have just rev1.1
