What is confusing about the use of local labels by the compiler?
There are many of these labels in the x86_64 output and none in the x86
output. I can't piece together how they're being used.
The x86_64 output also sports a .section eh_frame despite the fact that
I'm not using g++, which seems to just contain some data layout
description of the above labeled items.
I'm using gcc 4.3.2 if that matters.
