The issue is that with the above change one needs to use GDB 7.5 or later (or at least have the constant class DW_AT_high_pc support patch backported to GDB 7.4.*). Mark, can you point to the commit with the fix?

I don't understand how I failed to notice them when comparing results; I probably mistakenly used an already-failing baseline. I'll look into this, thanks.
