What's going on is that there is a second, presumably unrelated,
problem, the existence of which I had forgotten.  Following is a
shell script that reproduces the problem.  When I execute it under
binutils 2.13, with or without the patch, it dumps core;
under binutils 2.12, it doesn't.

I wonder ... can you reproduce it on your end?
