FWIW starting at /usr/include/dmd/druntime/import/core/stdc/stdio.d(1121)::
         asm nothrow @nogc
         {
             mov EDX, num;
             lock;
             inc _iSemLockCtrs[EDX * 2];
so nothrow isn't being seen as appropriate at the beginning of an asm 
block.  After that I think it gets confused as 1123 doesn't HAVE a brace 
(i.e. curly bracket) in it.
