Here is the reduced testcase (I think this is a Darwin specific bug 
meaning
the Darwin's backend does not expect the variable to change to being a
common symbol from a non-common, I will be looking into this, Darwin's 
backend
might just have to be rewritten, I already rewrote the PIC code part
The right asm does not have ".comm __ZN5ctypeIcE2idE,1" but
         .globl __ZN5ctypeIcE2idE
.data
__ZN5ctypeIcE2idE:
         .space 1
So it looks like unit-at-a-time is marking _ZN5ctypeIcE2idE 
(ctype<char>::id)
as a common symbol but it did it after Darwin's backend saw it as a 
non-common.
