 That's a merge error of some kind probably.  Overall we're under-tested. 
:(  No surprise given the number of corner cases.  And MIPS16 support 
seems to suffer particularly badly -- we've got just a couple of test 
cases AFAICT.  And the GCC or GDB test suites do not cover binutils 
functionality too well -- regressions of this kind if they happen there, 
mostly trigger by accident.
