--- Comment #3 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
It isn't clear from the bug what OS or set of header files where used to
generate the dwarf.  It would be ideal to include a pre-processed reduced
testcase to help in analyzing this bug.

You can use:

/your/version/gcc -E <whatever_flags_you_used> -c foo.c -save-temps

-save-temps will create the preprocessed foo.i automatically.  Then, reduce
this foo.i to the bare minimum, and attach it to this PR.

Also, what flags did you use for GCC in order to get this faulty behavior?

What flags did you use for readelf, or eu-readelf, etc?

Here are some general guidelines for reporting bugs for GCC:
