Sure, as soon as I figure out why my dmd produces different object code than yours. I ran a simple hello world executable and the "hello world" string is not properly aligned in the resulting executable, causing garbage to be appended by printf. The bug is somewhere between the parsing, which works fine, and the object generation (the call to obj_bytes() has the proper data pointer, but incorrect nbytes count).
