--- Comment #3 from Cary Coutant  ---
The internal error is fixed on trunk. The test case will now produce an error
that we cannot handle a branch into a merge section, which is (currently)
expected behavior. If you need to be able to handle branches into a merge
section during relaxation, please file a separate enhancement request.

--- Comment #1 from Cary Coutant  ---
I may have a fix for the internal error, but that just leads to this:

$ ../ld-new bug.o
../../ld-new: error: bug.o: cannot handle branch to local 6 in a merged section
.rodata.cst16

Are you expecting that error?
