Yup. Thanks. Worked. -O3 to -O2.

  Daniel,

This was fixed in elfutils on September 20, 2017:

https://sourceware.org/git/?p=elfutils.git;a=commitdiff;h=b10d7eb74064c5906f031cd17c0f82041c6a4ca1

the most recent release of elfutils (0.170) dates to August 3, 2017.

The elfutil developers really should put out another release.

You can either apply the patches in the above URL, or checkout the elfutils
source tree via git:

https://sourceware.org/elfutils/

However, the above does not explain why others have not encountered this
bug in LFS 8.2 - I suppose you are compiling with -O3 which is needed
to trigger the bug. So, another option would be to compile with -O2


  Cheers,

  Mike Shell

Any ideas? The host is LFS 8.1.
