I took a quick look.  readelf -w can be used to look at the debug info.
  The functions debug info looks OK.  The function has been inlined, and
there is out out-of-line instance of it.

readelf does report an error
readelf: Error: Not enough comp units for .debug_lines section
but this seems to be harmless.  I would guess that this is a
gcc/binutils problem with unused sections being optimized away in the
linker.  So we just are optimizing away all of the unused debug info.

I tried gdb 6.1, and it seemed to work fine.  I could step through the
function after setting a breakpoint there.
