Compilation error in abcstdlibs_more

[stopiccot]

Thanks to recent commits SDK becomes more stable but here is another error. This time I have no idea what is going on because it seems to be a segfault in llvm internals.

Any progress on this issue?

[cbakgly]

LLVM modified its partial procedure which led to null pointer in clobber register array. By comparing to previous version, you will find it if you want to take a deeper look and make change. Currently I am not working on this. Please expect future commits.

BTW, any comment on how to make this product better is welcome. We are quite open! :)
