The problem is that one of the flags that -cpu core2duo enables is 
implemented incorrectly, so it leads to .net breakage.

These flags are pni, lm, nx, ssse3, syscall.

Please try -cpu core2duo,-pni,-lm,-nx,-ssse3,-syscall.  If it works, 
remove features one by one until it doesn't and let us know the results.
