I have downloaded and installed Version 8.0 RC7. When I tried to check it out on several recent projects, many of them failed to re-compile with error 3114 (asm problem). If I turned the optimizer OFF the errors went away. Some of them could be corrected by re-arranging the code. The attached snippet contains two stubborn ones that I haven't been able to cure by re-arrangement (though you will see from the 2nd example, that I tried). The main program is compiled as a Win-64 console program. Running under Win7, fully updated.
