Comment:

 We're generating code like
 {{{
 .globl _ZCMain_main_info
 _ZCMain_main_info:
 Lc27e:
 n27l:
         leaq -16(%rbp),%rax
         cmpq %r15,%rax
         jb Lc27f
 Lc27e_end:
 Lc27g:
 n27s:
         subq $8,%rsp
 n27u:
         movq %r13,%rax
         movq %rbx,%rsi
         movq %rax,%rdi
         ...
 }}}
 and the symbols `n27l`, `n27s` etc. are not local symbols, so the linker
 seems to think that `n27s` is the end of `_ZCMain_main_info` and is
 stripping out the "dead code".
