Yeah, I know.  Simon and I have been running through this offline.

That's the conclusion I was coming towards.  We tried comparing the
mangled names in the two .o files (via objdump --demangle) and they
seemed identical.  Simon had to leave, so we didn't get any further.

Strange.  I find it amazing that this problem has only just arisen.
