Thanks for the file, it is indeed pretty big :)
But I am not able to replicate the issue with elfutils from git trunk.
commit 31c8b3f098b0654db8f573b2a15d5b6d07d4d3b0
If I do:
$ export LD_LIBRARY_PATH=/opt/local/install/elfutils/lib
$ /opt/local/install/elfutils/bin/eu-strip \
-o chrome_elfutil_test.stripped \
-f chrome_elfutil_test.debug chrome_elfutil_test
then the sections seem to come out correctly:

And both the produced chrome_elfutil_test.stripped and
chrome_elfutil_test.debug files seem valid ELF files.
But you might not be using the upstream build system, and you might use
different flags to call it. So, two questions. How did you build your
eu-strip binary? And how do you invoke it?
Thanks,
Mark
