I should have put this in darwin.h and called it from there. I think
that there is a far more fundamental problem that affects more than
Objective-C. Even with C code, we place a null string in a writable
section, which isn't correct. I've attached the .bc file. The culprit
is the @"\01LC" global. (This is generated with my hack, so it has an
explicit "section".) Any suggestions for a back-end fix would be
welcome, as I'm not a huge fan of hacking the front-end to get the
sections for symbols correct. :-)
