This is all running in a virtual box.
And we still have the problem so we are considering options.

a) Try out if different virtual machine images change the situation.
b) Compile qt without "-O2".
   What is the easiest way to compile qt without "-O2"?
   (I did not find a good way. It seems that configure.exe or mingw32-make
    will just use -O2 while building qt.)
