Fix for mysterious x86 division crash.

Jun from Intel reported some crashes occuring with the official
Intel SDK system images and the latest emulator binaries (from SDK
Tools 22.6 or higher).

This patch should fix the issue, until we actually update the whole
source code to completely replace the implementation (due to the
refactoring effort).
