I don't know of pdp11 ELF code in binutils.  

The named-section stuff itself doesn't seem to be directly related.  If I run the test with the target flag -mdec-asm, it still fails.  That mode does support named sections.

I can easily see the issue with the debugger and compare with a target that works (vax).  So I should be able to find this, at least once I figure out how to turn off address space randomization on my host.
