I think you got me wrong there. I have no problems building the whole Qt (including QtCore) with -O3 flag. It builds just fine, and cc1plus.exe is not crashing. I'm saying that rather applications based on the resulting QtCore.dll are crashing, and the trace shows that this is because of QtCore.dll itself. Once again, rebuilding QtCore.dll with -O2 solves the issue: it stops crashing.
